ON Semiconductor introduces micropower step-up DC-DC converter

February 12, 2001–Phoenix, Arizona–ON Semiconductor today announced the availability of a DC-DC converter that extends battery usage in portable equipment powered by one or two battery packs. With an efficiency rating of 85%, the NCP1402 micropower power factor modulator (PFM) step-up DC-DC converter boasts an output voltage of 1.9V, enabling longer battery life.

Available in a low-profile 5-pin SOT-23 package, the converter offers a 60% reduction in footprint when compared to the MC33463, the previous generation product. A small package size, coupled with improved features such as higher efficiency, higher current output, and lower noise specifications than competitive products, the NCP1402 DC-DC controller is ideal for applications that include handheld instruments and games, camcorders, MP3 players, digital cameras, and portable communications devices.

Equipped with an on-chip PFM oscillator, controller, and comparator, a voltage reference, soft-start feedback resistors, driver and power MOSFET switch with current limit protection, the NCP1402 is designed to start-up with a cell voltage of 0.8V and operate down to less than 0.3V.

The NCP1402 is available in a 5-pin TSOP package with five standard regulated output manufactured in quantities of 12,000 pieces, priced at $0.40.
