MULTISWITCH_CHARGE_PUMP_BOOST_CONVERTER

Published:2009/7/12 22:47:00 Author:May | From:SeekIC

This device is useful both in main supplies and in backup supplies. It generates a regulated 5-V output for load currents to 20 mA and inputs ranging from 1.8 to 3.6 V. For input voltages no lower than 3 V, the output current can reach 50 mA. The circuit accomplishes regulation without a linear pass element, but its losses are the same as those of an unregulated doubler or tripler feeding into a linear regulator.
