NCP5007
Compact Backlight LED
Boost Driver
The NCP5007 is a high efficiency boost converter operating in a
current control loop, based on a PFM mode, to drive White LEDs. The
current mode regulation allows a uniform brightness of the LEDs. The
chip has been optimized for small ceramic capacitors and is capable of
supplying up to 1.0 W output power.
