NCP1403

NCP1403 Boost Converter - PFM, DC-DC 15 V, 50 mA The NCP1403 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. 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 mA (No Switching) Low Shutdown Current of 0.3 mA 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 Typical Applications LCD Bias Personal Digital Assistants (PDA) Digital Still Camera Handheld Games Hand−held Instrument http://onsemi.com 5 1 TSOP−5 SN SUFFIX CASE 483 MARKING DIAGRAM AND PIN CONNECTIONS CE 1 FB 2 VDD 3 DCEAYWG G 5 LX 4 GND (Top View) DCE =Specific Device Marking A = Assembly Location Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION Device Package Shipping† NCP1403SNT1 TSOP−5 3000/Tape & Reel NCP1403SNT1G TSOP−5 3000/T...
