LYTSwitch-2 series LED Driver AC-DC Converters The LYTSwitch-2 family of primary-side AC-DC converters from Power Integrations is designed for LED driver applications in sold state lighting. These devices dramatically simplify low power constant-current LED driver solutions by eliminating the opto-coupler and secondary control circuitry. They incorporate a high-voltage switching MOSFET plus control circuitry in a compact monolithic IC which requires very few external components. Typical applications include LED lamps and down-lights, luminaires, ballasts and T8 tubes. ? Accurate constant-current regulation, typically ±3% ? Automatic compensation for transformer inductance variation, external component changes with temperature and input line voltage variations ? Elimination of opto-coupler and secondary control circuitry ? Elimination of control loop compensation circuitry ? Frequency-jitter greatly reduces EMI filter cost ? Programmable switching frequency reduces required trans
