Internal transfomer provides galvanic isolation between primary and secondary sides. Reduce emitted electro-magnetic interference (EMI) to improve system reliability and improve chances of passing government radiated emissions standards. Shielded inductors, Pi-ilters, switch gate drive control and PCB layout exemplified by the demo board reduce EMI. These devices are certified to meet EN55022B with margin. Power and dim (up to a 3000:1 ratio) LEDs with as few as three external components. Integrated inductor, switches, LED current controller and compensation are incorporated in a LGA package. Maintain a regulated output voltage while the input voltage could fluctuate above, below or equal to the desired output voltage with a small PCB footprint. The buck-boost controller seamlessly transitions the internal H-bridge power switches between buck and boost operation. Choose from a wide range of regulated output voltage options from 0.6V to 34V that are tailored to meet the specific operating requirements of loads from FPGAs and SoCs to high performance ADCs and amplifiers up to intermediate bus voltages. A combination of state of the art Mid & High Voltage Wafer Processes, superb IC design and characterization create a wide portfolio of products each targeted to meet the specific needs. 15 x x 15 9 x 15 9 x x x 6.25

27 LINEAR AUTOMOTIVE & TRANSPORTATION SOLUTIONS 25 Active Battery Balancing ICs Electric vehicles (EV) and plug-in hybrid vehicles (PHEV) are demanding longer usable run time from their battery stacks. These stacks of batteries are typically made of battery modules, each with as many as 12 Li-Ion cells stacked in series, offering a ~40V battery module. As the battery run time defines the very feasibility of these vehicles, maximizing battery capacity is of primary importance. Batteries can always be made larger to improve driving range, but this increases the weight, size and cost of the vehicle. So the goal for automotive EV IC designers is to find ways to make the existing battery run longer. One effective method is to employ active balancing.
