1 Features  
3 Description  
AEC-Q100-qualified for automotive applications  
– Device temperature grade 1: –40°C to +125°C  
ambient operating temperature  
– Device HBM classification level 2  
– Device CDM classification level C6  
96% Peak efficiency while converting 12 V to 5 V  
Low EMI and minimized switch node ringing  
400-kHz (±10%) fixed switching frequency  
–40°C to +150°C junction temperature range  
External frequency synchronization  
RESET output with internal filter and 3-ms release  
timer  
Automatic light load mode for improved efficiency  
Pin-selectable forced PWM mode  
Built-In compensation, soft start, current limit,  
thermal shutdown, and UVLO  
0.35-V dropout with 3.5-A Load at 25°C (Typical)  
18-µA IQ_VIN: quiescent current at 3.3 VOUT and no  
load (typical)  
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.  
Output voltage: 5 V, 3.3 V, and ADJ (1 V to 20 V)  
±1.5% reference voltage tolerance
