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.
