LM61440-Q1 - Texas Instruments

LM61440-Q1 Automotive Low EMI Synchronous Step-Down Converter

The LM61440-Q1 is an automotive-focused, high-performance, DC-DC synchronous step-down converter. With integrated high-side and low-side MOSFETs, up to 4 A of output current is delivered over a wide input range of 3.0 V to 36 V; tolerant of 42 V, easing input surge protection design. The LM61440-Q1 implements soft recovery from dropout eliminating overshoot.
