PowerInt LYTSwitch－0系列12 W LED T8管灯电源解决方案
PowerInt公司的LYTSwitch-0系列产品是专门用来驱动低成本LED灯和T8管灯的IC,集成了700V功率MOSFET,振荡器,ON/OFF控制方案,EMI降低电路和控制功能包括限流和热关断等.本文介绍了LYTSwitch-0系列产品主要特性, 12 W LED T8管灯电源解决方案主要特性和指标,电路图,材料清单和PCB布局图.
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.
LYTSwitch-0系列产品主要特性:
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
