NCP5010
500 mW Boost Converter for White LEDs
The NCP5010 is a fixed frequency PWM boost converter with integrated rectification optimized for constant current applications such as driving white LEDs.
This device features small size, minimal external components and high−efficiency for use in portable applications and is capable of providing up to 500 mW output power to 2−5 series connected white LEDs.
A single resistor sets the LED current and the CTRL pin can be pulse width modulated (PWM) to reduce the LED Current.
The device includes True−Cutoff circuitry to disconnect the load from the battery when the device is put into standby mode.
