HT7L4661 - Active PFC Non-isolation Buck LED Lighting Driver
The HT7L4661 is a Buck converter controller using quasi-resonant conversion technology.
It can be used for driving high-brightness LEDs with power factor correction in off-line applications.
The controller is implemented by driving an external power MOSFET and measuring and regulating a constant LED
HT7L4661 Features
* in the device include a rapid high voltage startup function and a 5V LDO output with a 1mA drive capability for external loads. There is also a linear dimming function to adjust the LED illumination level. The device also includes multiple protection features to protect it from fault conditions. The
