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 highefficiency for use in portable
applications and is capable of providing up to 500 mW output power
to 25 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 TrueCutoff circuitry to disconnect the load
from the battery when the device is put into standby mode. To protect
the device, an output overvoltage protection, and short circuit
protection have been incorporated. The NCP5010 is housed in a low
profile, space efficient 1.7 x 1.7 mm FlipChip package. The device
has been optimized for use with small inductors and ceramic
capacitors.
