SNAS714B – NOVEMBER 2016 – REVISED MARCH 2018 LMS3635-Q1 3.5-A, LMS3655-Q1 5.5-A, 36-V Synchronous, 400-kHz Step-Down Converter
1 Features 3 Description The LMS3635-Q1 and LMS3655-Q1 synchronous
buck regulators are optimized for high performance
applications, providing an output voltage of 3.3 V, 5
V, or an adjustable output of 1 V to 20 V. Seamless
transition between PWM and PFM modes, along with
a low quiescent current, ensures high efficiency and
superior transient responses at all loads. 1 AEC-Q100 Qualified for Automotive Applications
