IC revisionA

Description

The LM61430-Q1 is a high-performance, DC-DC synchronous step-down converter. With integrated high-side and low-side MOSFETs, up to 3 A of output current is delivered over a wide input range from 3.0 V to 36 V tolerant of 42 V, easing input surge protection design. The LM61430-Q1 implements soft recovery from dropout eliminating overshoot on the output.
