AP2007SPER

The AP2007 is a compact, high-efficiency, synchronous step-up converter with power Mosfets embedded and with output turn off true shutdown function for a single-cell Li-ion/polymer battery. The AP2007 uses only 70μA (typ) quiescent current and allows the converter to switch only when needed at no load and light loads, and when load is higher than 150mA, it uses fixed-frequency PWM technique at 1MHz. It features a current mode control for fast transient response with internal compensation. The AP2007 includes cycle-by-cycle current limit to maximum inductor current and over-temperature protection circuit. The AP2007 is suitable for iPad-like computers, smart phones and portable handheld devices. The AP2007 is available in a SOP8-PP package. The operating temperature range is from -45°C to +85°C.
