LYTSwitch-0 Series AC/DC发光二极管驱动器集成电路 :

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.

• High power factor meeting EU and USA requirements
• Very low component count
• Frequency jitter reduces EMI
• No bias supply or transformer required
• Integrated auto-restart for short-circuit, open-circuit and open loop faults
• Hysteretic over temperature protection (135°C) provide extensive protection at no additional cost
• Buck, buck-boost non-isolated flyback, and boost architectures
• Applications: Commercial & Industrial lighting, Indoor lighting, Outdoor lighting.
