1 Technical Z-Power LED Data X090 Sheet Application Note Designing with Acrich Introduction Acrich is designed to connect directly to AC source via wires with no AC/DC converter which is essential for conventional general lighting. As there is no need of converter, Acrich can realize as close life-time as original LED and make a better use of a space in many applications. W MR W Bulb Features Directly connect to AC power using a Acrich IC High power efficiency High power factor Low THD Long life time The simplest BOM Miniaturization Lead free product RoHS compliant Also, Acrich s high power factor can show best energy saving effect in many lighting applications. 8W module W module Applications Replacement lamp Down light Ceiling light Industrial Light W module August 0

3 Technical Z-Power LED Data X090 Sheet. Driver Configurations. Description Acrich IC has a direct-driving architecture that drives Acrich directly from AC supply, without AC-DC conversions. Acrich IC has 8 channels, and activations of these channels and their current flows are controlled by its internal controller so that Acrich currents, power dissipation and power factor are regulated within proper ranges. Acrich IC integrates all peripheral components including bridge diodes and passive components, providing a simple and effective solution for LED light applications. 8W 8X8mm W Xmm Figure. Acrich IC PKG ( LGA) Features - High power efficiency - Reduce lamp weight - Flicker improvement - Low circuit cost - No lifespan reduction by secondary components Specifications - AC input range - Rated power - Power efficiency - Total harmonic distortion - Power factor - Life time 90~0V(00V)/00~V(0V)/00V~V (0V/0V/0V) W / 8W 90% % 0.9 8,000hrs August 0

11 Technical Z-Power LED Data X090 Sheet. Surge Protection Circuit A metal oxide varistor (MOV) is often used to protect lighting systems from electrical surges and ring-wave effects, and help manufacturers meet safety and performance standards. The MOV prevents short-duration voltage impulse. Lightning tests (IEC 000--) and ring-wave Tests (IEEE C..) can be used for these real-life threat simulation in the lab. A surge protection circuit (SPC) consists of two components (MOV & fusible resistor) and it is not necessary for normal operation of the Acrich IC module. Fig. Surge Protection Circuit Table.
