No.11040EAT40
●Description
The BD6076GUT is a white LED driver IC with synchronous rectification that can drive up to 4LEDs.
With synchronous rectification (no external schottky diode required) and small package, they can save mount space.
And the brightness of LED can be adjusted by using PWM pulse on EN pin.
●Features
1) Synchronous rectification Boost DC/DC converter
2) No external schottky diode required
3) Driving 4 series white LEDs
4) Internal Load Disconnect SW
5) Over voltage protection
6) Protect open and short output
7) Thermal shut down
8) Brightness adjustment by external PWM pulse
9) Small and Thin CSP package in 8pins
●Applications
White LED Backlight
Torch light and easy flash for camera of mobile phone
