AC/DC Conversion SMPS IGBTs/Stealth Rectifiers SMPS IGBTs are manufactured with Fairchild s new SMPS technology offering better V SAT /E OFF trade-off. This is achieved through a new top-side structure and better epi and lifetime control allowing the manufacture of devices with less than half the previous generations E OFF. Additionally, this control smooths the switching waveforms for less EMI. SMPS IGBTs are manufactured using stepper based technology which offers better control and repeatability of the top side structure, thereby providing tighter specifications.

One key differentiator is the inclusion of isolation. In most cases this is a safety requirement, but the transformer can also provide a number of benefits especially if the ratio between input and output voltages is high. Although this section focuses on common isolated designs, the MOSFET requirements of a non-isolated or buck style converter, used in computer designs and VRMs are very similar to those used on the output or secondary stage of these converters. Isolated DC/DC Converter Primary Switch Requirements Typically MOSFETs with breakdown voltages between 60-200V are used depending on the input voltage and topology For the Forward converter and other single switch designs where transformer leakage current can generate high transient voltages, 100V and 200V devices are common for 24V and 48V telecom systems For the half-bridge and other multi-switch topologies 60V through to 100V are common in telecom, datacom and server applications For high efficiency, MOSFETs need to be optimized for the lowest combination of switching and conduction losses and the appropriate die size must be selected for a given power rating and switching frequency MOSFETs should not generate high losses in any discrete or I.C. driver circuitry There should be good immunity to self turn on resulting from high dv/dt on the MOSFET drain. This is especially true in bridge topologies when snappy MOSFET body diodes come out of reverse recovery Rugged in over-voltage transient conditions, otherwise known as avalanche Available in Low R θjc packaging from SuperSOT-6 to TO-247 6

The combination of both low gate charge and low R DS(ON) improve converter efficiencies as switch currents increase.

The most typical output voltages are 5V. Lower voltage MOSFETs can be used if the input voltage range is limited by a pre-regulator stage. This adds complexity, but allows lower R DS(ON) MOSFETs for a given die size. For high efficiency the MOSFETs need to be optimized for the lowest conduction loss to gain the biggest advantage over Schottky rectifier technology. Switching losses are also important, especially if a discrete gate driver is used, but many topologies use the transformer to generate the MOSFET gate signals and low gate charge is not the dominant factor. For high reliability, the MOSFETs must be rugged in over-voltage transient conditions, otherwise known as avalanche Devices available in Low R θjc packaging from SuperSOT-6 to TO-263 8

Reduced Miller charge or drain to gate capacitance for high turn on immunity with high drain dv/dt Rugged in avalanche with good safe operating area capability Design Considerations Maximum secondary rectifier RMS current handling capability is dependent on the device R DS(ON), thermal path, body diode conduction time, switching losses, and potential avalanche losses.

Uninterruptible Power Supplies Off-Line UPS The off-line UPS (uninterruptible power supply) switches the power load to battery backup power to allow the user to work through brief power outages or surges without data loss or inconvenient system downtime. In applications such as UPS where switching speed, low R DS(ON), and power dissipation are critical, Fairchild UltraFET technology devices provide the highest levels of performance in the market. Designed for 300-2kW off-line UPS DC/DC converters, AC/DC inverters, DC/DC power supplies, and general purpose load control applications in mind, Fairchild s UltraFET MOSFETs have been designed to optimize R DS(ON), Q g, and body diode (Q RR & t rr ) characteristics to provide a fast and efficient device for switching applications utilizing topologies such as half-bridge and full-bridge. In inductive load applications such as UPS and motor control, a relevant figure-of-merit is {R DS(ON) * (Q RR /t rr )}. Off-Line UPS Specific Benefits Lower R DS(ON) in a reduced package size = less conduction losses Reduced Q g = less switching losses Specifically doped to exhibit soft body diode characteristics (low Q RR and t rr ) Capable of withstanding high energy in the avalanche mode, dissipates less power Better thermal characteristics = more rugged Higher performance than most competitors Optimized die size = lower price and reduced size Devices Available in Various Current Ratings and Package Combinations* R DS(ON) Q g (typ) Q g (max) Q RR(MAX) t rr(max) BV DSS Part Number Package Amp Ω nc nc nc ns UPS Fig of Merit 55V HUF75307P3 TO-220 15 0.090 9 11 55 45 0.1100 HUF75321P3 TO-220 35 0.034 21 26 82 59 0.0473 HUF75329G3 TO-247 49 0.024 35 43 120 72 0.0400 HUF75332G3 TO-247 60 0.019 40 50 140 75 0.0355 HUF75337P3 TO-220 75 0.014 51 61 180 85 0.0296 HUF75339G3 TO-247 75 0.012 60 75 160 85 0.0226 HUF75343G3 TO-247 75 0.009 92 110 200 100 0.0180 HUF75344G3 TO-247 75 0.008 90 108 210 105 0.0160 HUF75345P3 TO-220 75 0.007 125 165 225 110 0.0143 80V HUF75542P3 TO-220 75 0.014 80 96 255 102 0.0350 HUF75545P3 TO-220 75 0.010 105 125 300 100 0.0300 100V HUF75623P3 TO-220 22 0.064 23 28 313 100 0.2003 HUF75631P3 TO-220 33 0.040 35 42 400 112 0.1429 HUF75637P3 TO-220 44 0.030 48 58 305 105 0.0871 HUF75639G3 TO-247 56 0.025 57 75 320 110 0.0727 HUF75639P3 TO-220 56 0.025 57 75 320 110 0.0727 HUF75645P3 TO-220 75 0.014 106 127 360 145 0.0348 HUF75652G3 TO-247 75 0.008 211 255 490 150 0.0261 150V HUF75842P3 TO-220 43 0.042 77 90 1080 190 0.2387 HUF75852G3 TO-247 75 0.016 215 260 1830 260 0.1126 200V HUF75925P3 TO-220 11 0.275 25 30 800 180 1.2222 HUF75939P3 TO-220 21 0.130 52 63 1680 378 0.5778 HUF75945G3 TO-247 38 0.071 97 117 3110 700 0.3154 HUF75945P3 TO-220 38 0.071 97 117 3110 700 0.3154 * The devices in the table above are more cost effective solutions than RFP40N10, RFP50N06, RFP70N06, IRFZ44N 12

Uninterruptible Power Supplies On-Line UPS An on-line UPS constantly runs connected equipment on recreated AC power. The UPS converts incoming AC utility power into DC power and then back into clean AC power to operate your equipment. This double conversion process ensures consistent power quality that s completely isolated from any utility power disturbances. If the utility AC power fails, the UPS continues to run using its internal battery to provide the DC power which is converted to clean AC power for use by the load. This method of conversion involves the use of SMPS (switch mode power supply circuits). The heart of these circuits is the power semiconductor device. In choosing a power switch for applications such as the on-line UPS, designers should take into account the losses incurred in the circuit during different operational states. In the on-state the device allows current to flow with some power being lost due to the voltage seen across the device multiplied by the current through the device. This is known as conduction losses. When the device switches from the conduction state to the blocking state and vice-versa, energy is lost in the transition. This is known as switching losses. The SMPS IGBT has the lowest total losses (switching losses and conduction losses) in the smallest package compared to the alternative design. This allows the UPS designer to create a high power density and less expensive system. The SMPS IGBT and Stealth Diode are optimized devices that set the foundation for longer battery life by being more efficient switches. The SMPS IGBT and Stealth Diode (individually or co-packed) are designed specifically to provide enhanced output power quality in smaller, lighter, and more cost efficient designs. Fairchild offers a complete portfolio of power products for UPS applications: SMPS IGBTs, Stealth Diodes, IGBT Modules, Advanced High Voltage MOSFETs.

Larger packages can be considered. The IGBT structure does block out the body diode that exists in MOSFETs so we offer these IGBTs with or without a co-packed rectifier.
