NCP9003
Compact Backlight LED
Boost Driver
The NCP9003 is a high efficiency boost converter operating in
current loop, based on a PFM mode, to drive White LED. The current
mode regulation allows a uniform brightness of the LEDs. The chip
has been optimized for small ceramic capacitors, capable to supply
up to 1.0 W output power.
