Packages
LM2735-Q1 is AEC-Q100 Grade 1 Qualified and
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%. 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 shutdown features an
ultra-low standby current of 80 nA ideal for portable
applications. Tiny SOT-23, WSON, and MSOP-
PowerPAD packages provide space-savings.
Additional features include internal soft-start, circuitry
to reduce inrush current, pulse-by-pulse current limit,
and thermal shutdown.
is Manufactured on an Automotive Grade Flow
