DESCRIPTION

The SiP1759 is a buck-boost regulating charge pump. It is designed to provide a regulated output from 1 cell Li Ion or 2/3 cell NiMH voltages found in handheld portable equipment, 1.6 V to 5.5 V. SiP1759 allows the option of a fixed 3.3 V output voltage, or an adjustable output which can be set from 2.5 V to 5.5 V. The output current is up to 100 mA.
