Compact Backlight LED

Boost Driver

The NCP5006 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.

Features

• 2.7 to 5.5 V Input Voltage Range

• Vout to 24 V Output Compliance Allows up to 5 LEDs Drive in

Series

• Built−in Overvoltage Protection

• Inductor Based Converter brings up to 90% Efficiency

• Constant Output Current Regulation

• 0.3 mA Standby Quiescent Current

• Includes Dimming Function (PWM)

• Enable Function Driven Directly from Low Battery Voltage Source

• Automatic LEDs Current Matching

• Thermal Shutdown Protection

• All Pins are Fully ESD Protected

• Low EMI Radiation

• Pb−Free Package is Available

Typical Applications

• LED Display Back Light Control

• Keyboard Back Light

• High Efficiency Step Up Converter
