SNVS485G – JUNE 2007 – REVISED AUGUST 2015 LM2735-xx 520-kHz and 1.6-MHz Space-Efficient Boost and SEPIC DC-DC Regulator
1 Features 3 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%. Current-mode control and internal
compensation
provide
ease-of-use,
minimal
component count, and high-performance regulation
over a wide range of operating conditions. External …
