NCP5021 high voltage white LED driver circuit
This high voltage white LED driver circuit is based on the NCP5021 IC manufactured by On Semiconductor. This NCP5021 high voltage white LED driver circuit is designed with ambient light sensing feature.
The NCP5021 is capable of driving up to 8 LEDs in series for portable backlight applications.
The built−in DC DC converter is based on a high efficient PWM boost structure with 32 V output voltage span.
The high voltage white LED driver circuit is very simple, requiring few external electronic parts and it can be connected through an I2C protocol to another device or microcontroller.
The circuit application for the NCP5021 require just few external components as you can see in the circuit application from the schematic bellow .
