Description

The LYTSwitch-0 family is specifically designed for low cost LED bulb and T8 tube applications. LYTSwitch-0 devices monolithically integrate a 700 V power MOSFET, oscillator, ON/OFF controller scheme, EMI reduction and control functions including cycle-by-cycle current limit and thermal shutdown circuitry into one IC.

Product Highlights

Cost-Effective

The LYTSwitch-0 family enables low component-count, non-isolated switching topologies for highly cost competitive LED lighting applications.

66 kHz operation together with frequency jittering insures a very low EMI filter cost.

Start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry.

Power Factor Correction

The LYTSwitch-0 family enables designs that easily meet European and North American standards for PFC in consumer lighting applications.

Tight CC Performance

Accurate CC with tight line and load regulation that is stable over a wide temperature range makes the LYTSwitch-0 ideal for LED lighting applications.

Comprehensive Protection

Integrated auto-restart for short-circuit, open-circuit and open loop faults as well as a hysteretic over temperature protection feature (135 °C) provide extensive protection at no additional cost.

Supports Different LED Applications

Buck, buck-boost non-isolated flyback, and boost architectures are all supported by the LYTSwitch-0 family. The 700 V switching power MOSFET supports an input voltage range of 85 VAC to 308 VAC.

Package options for thru-hole and surface-mount suit different manufacturing requirements.
