内置高压启动无VCC电容隔离型LED恒流驱动芯片描述SDH7611S是一款高精度、低成本的原边反馈LED恒流驱动芯片，应用于反激隔离LED照明。

芯片工作在电感电流断续模式，适用于90Vac~265Vac 输入电压、5W输出功率。

SDH7611S集成650V高压功率MOS，内置高压启动电路，无需启动电阻和辅助绕组即能实现芯片的自主供电；SDH7612S无需外部VCC电容；极大节省了系统成本。

SDH7611S内部集成多种保护功能，包括过压保护，过热调节等，增强了系统安全性和可靠性。

SDH7611S采用SOP-7-255-1.27封装。

1.启动控制SDH7611S集成了高压启动供电电路，无需启动电阻和辅助绕组供电。

芯片通过HV端直接从高压端口取电，给内部电源VCC供电，极大的简化了外围电路，同时也减小了系统启动时间。

系统上电后，芯片通过HV端、经过高压启动电路给VCC电容充电，当VDD电压达到芯片开启阈值时，芯片开始工作；VCC内部有钳位电路；功率管每次导通时，瞬间会有比较大的导通损耗，VCC会瞬间掉电，高压供电模块会立即给VCC供电，重新把VCC冲到钳位电压。

2.恒流控制LED输出电流计算公式为：其中Np是变压器源边匝数；Ns是副边匝数。

Vcs为内部基准电压，0.6V。

Rcs为电流采样电阻。
