LED Driver ICs Handle Up to 22 W

11 June 2016

Power Integrations has announced its LYTSwitch™-1 single-stage, non-isolated, buck topology LED driver IC family. Featuring a very compact footprint, the IC enables the design of LED bulbs and tubes with high constant-current accuracy while using a minimum number of components. A novel driver algorithm ensures high power factor (PF) and low total harmonic distortion (THD) while maintaining very high efficiency.

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.

LYTSwitch-1 IC samples are available now. Devices are priced at $0.26 in 10,000-piece quantities. Reference design DER-548 is available for download now from the Power Integrations website.
