NCP5006

NCP5006 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 www.onsemi.com 5 1 TSOP−5 SN SUFFIX CASE 483 MARKING DIAGRAM 5 DCSAYWG G 1 DCS = Device Code A = Assembly Location Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) PIN CONNECTIONS Vout 1 GND 2 5 Vbat FB 3 4 EN (Top View) ORDERING INFORMATION Device Package Shipping† NCP5006SNT1 TSOP−5 3000 Tape & Reel NCP5006SNT1G TSOP−5 3000 Tape & Reel (Pb−Free) †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel...
