NCP5007 Description
NCP5007 pact 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.
