The KF6392 is a compact, high efciency, synchronous step-up converter with power MOSFETs integrated for a single-cell Li-ion/polymer battery. This converter consumes only 100uA current when no

switching. When current load is light, this converter enters burst mode to obtain high efficiency. When current load is heavy enough, it entersuency PWM mode. It adopts peak current mode for fast transient response with internal compensation. This converter contains cycle-by-cycle current limiting and shot protection circuit. It is suitable for iPad-like computers, smart phones and portable handheld devices. The device is packed in ESOP8 package.
