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.
Features Inductor Based Converter brings High Efficiency Constant Output Current Regulation 2.7 to 5.5 V Input Voltage Range Vout to 22 V Output Compliance Allows up to 5 LEDs to be Driven
in Series which Provides Automatic LED Current Matching Built−in Output Overvoltage Protection 0.3 �A Standby Quiescent Current Includes Dimming Function (PWM) Enable Function Driven Directly from Low Battery Voltage Source Thermal Shutdown Protection All Pins are Fully ESD Protected Low EMI Radiation Pb−Free Package is Available
