NCP1403SNT1G Datasheet

DC/DC Switching Converters


The NCP1403SNT1G is a monolithic PFM step−up DC−DC converter. This device is designed to boost a single Lithium or two cell AA/AAA battery voltage up to 15 V (with internal MOSFET) output for handheld applications. A pullup Chip Enable feature is built with this device to extend battery−operating life. Besides, the device can also be incorporated in step−down, and voltage−inverting configurations.This device is available in space−saving TSOP−5 package. NCP1403SNT1G Features • 82% Efficiency at VOUT = 15 V, IOUT = 50 mA, VIN = 5.0 V• 78% Efficiency at VOUT = 15 V, IOUT = 30 mA, VIN = 3.6 V• Low Operating Current of 19 A (No Switching)• Low Shutdown Current of 0.3 A• Low Startup Voltage of 1.3 V Typical at 0 mA• Output Voltage up to 15 V with Built−in 16 V MOSFET Switch• PFM Switching Frequency up to 300 kHz• Chip Enable• Low Profile and Minimum External Parts• Micro Miniature TSOP−5 Package• Pb−Free Package is Available NCP1403SNT1G Applications • LCD Bias• Personal Digital Assistants (PDA)• Digital Still Camera• Handheld Games• Hand−held Instrument
