General Description

The LM2735 device is an easy-to-use, space-efficient 2.1-A low-side switch regulator, ideal for Boost and SEPIC DC/DC regulation.

The device 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 520 kHz or 1.6 MHz, allowing the use of extremely small surface mount inductor and chip capacitors, while providing efficiencies of up to 90%.
