NCP5010 white LED driver circuit

Published:2011/8/29 2:37:00 Author:Lucas | Keyword: white LED driver | From:SeekIC

The IC integrates the rectification function, and it can provide 22V voltage, and the single resistor can be used to set the white LED current, and output power is up to 500mW, and it can drive 2 to 5 series of white LEDs. NCP5010 input voltage range is 2.7 ~ 5.5V, and the input efficiency can be up to 84% at 4.2V and 30mA, and the cut off current is 1μA with real cut, short-circuit and overvoltage protection, undervoltage cut off. In addition, due to its pulse width modulation (PWM) boost converter frequency is 1MHz, it integrates the Schottky rectifier.
