TinySwitch-LT集成了一个650 V的功率MOSFET、振荡器、高压开关电流源、电流限流(用户可选)及热关断电路。该IC产品系列采用ON/OFF控制方式,提供一个灵活的设计方案,并且实现更低的系统成本及更大的输出功率范围。

产品特色:

  • 额定值650 V的集成MOSFET
  • 简单的ON/OFF控制,无需环路补偿
  • 通过BP/M引脚电容值可选择不同的电流限流点
  • 更高的电流限流点可得到更高的峰值功率,或在敞开式应用中得到更高的连续输出功率
  • 严格的I2f参数公差范围降低系统成本;降低了最大过载功率,从而降低变压器、初级箝位及次级元件的成本
  • 导通时间延长 - 更低输入电压下维持输出的稳定/维持时间,可以使用更低容量的输入电解电容
  • 频率调制降低EMI滤波成本
