Housed in a compact SO-8 package, LYTSwitch-1 ICs are greater than 93% efficient with a PF of over 0.9 and THD as low as 15%. Devices can be used in a low-side buck topology for reduced EMI or in a high-side buck topology that simplifies design. Delivering up to 22 W without a heatsink, the universal input (100–308 VAC) ICs incorporate a 725 V MOSFET for high reliability. Designers can make use of small, off-the-shelf inductors due to a unique peak-current control algorithm. The devices meet all applicable international standards, including: DOE 6 (external power supply), CEC Title 20 and 24, ENERGY STAR® SSL, EN61000-3-2 (C) plus China and India standards.
In common with all Power Integrations products, LYTSwitch-1 LED driver ICs have a host of protection features, including thermal foldback with end-stop shutdown, short-circuit protection, input and output OVP, and overcurrent and SOA protection.
