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.
Advanced high-speed circuitry allows
the LMS3655-Q1 to
regulate an input of 24 V to an output of 3.3 V at a fixed frequency of 400 kHz
while also enabling a continuous load current of 5.5 A. An innovative frequency
foldback architecture allows this device to regulate a 3.3-V output from an input
voltage of only 3.5 V. The input voltage can range up to 36 V, with transient
tolerance up to 42 V, easing input surge protection design.
An open-drain reset output, with
built-in filtering and delay, provides a true indication of system status. This
feature negates the requirement for an additional supervisory component, saving cost
and board space.
