LYTSwitch-1 LED Driver ICs Reduce Complexity in Bulbs Tubes and Ballasts up to 22 W

Power Integrations 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 which 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 new 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.

Comments Hubie Notohamiprodjo, director of product marketing at Power Integrations: “Low system complexity and high performance make LYTSwitch-1 ICs ideal for both commercial and residential lighting applications. The low component count and compact size make these LED driver ICs easy to fit into space-challenged applications such as tube end caps, small form factor candles and GU10 bulbs, as well as low cost A19 and decorative-filament lamps.”
