LM2735XSD/NOPB Datasheet PDF - TI

●DESCRIPTION

●The LM2735 is an easy-to-use, space-efficient 2.1A low-side switch regulator ideal for Boost and SEPIC DC-DC regulation. It provides all the active functions to provide local DC/DC conversion with fast-transient response and accurate regulation in the smallest PCB area. Switching frequency is internally set to either 520kHz or 1.6MHz, allowing the use of extremely

●small surface mount inductor and chip capacitors while providing efficiencies up to 90%.
