LED IC HY2821
搭配PWM或PFM定電壓IC使用,將其應用轉換為定電流輸出藉以驅動LED電路
Description
The HY2821 is a Power LED Current Detector. It can let a normal PWM IC transfer to be a LED Driver, and adjust constant current level more easy. It can let your constant current tolerance reduce less than 1%.
Features
- Operation from 5V to 40V.
- Minimum sense current 200nA
- Minimum sense voltage 10mV.
- SOT23 5-pin small package.
Applications
- LED Lighting Applications.
