ON Semiconductor introduces the NCP1423 — a monolithic, micro-power, high-frequency step-up DC/DC switching converter that boosts the voltage from one or two nickel metal-hydride (NiMH) or nickel cadmium (NiCd) cells up to a usable level of 1.8 or 3.3 V. This device is designed for battery-operated portable electronic products, supplying up to 400 mA load — including wireless optical mice and keyboards, wireless headsets, audio players, PDAs and other handheld devices. The NCP1423 integrates synchronous rectification to improve efficiency and to eliminate the external Schottky diode. Its high switching frequency (up to 600 kHz) allows for a low profile, small-sized inductor and output capacitor to be used. When the device is disabled, the internal conduction path from the LX or BAT pin to the OUT pin is fully blocked — and the OUT pin is isolated from the battery.
