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.
