3 Description

The LM62440-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; 42-V

tolerance supports load dump for durations of 400

ms. The LM62440-Q1 implements soft recovery from

dropout, eliminating overshoot on the output.

The LM62440-Q1 is specifically designed for minimal

EMI. The device incorporates pseudorandom spread

spectrum, adjustable SW node rise time, a low-EMI

VQFN-HR package featuring low switch node ringing,

and an optimized pinout for ease of use. The

switching frequency can be synchronized between

200 kHz and 2.2 MHz to avoid noise sensitive

frequency bands. In addition, either 2.1-MHz or 400-

kHz frequency factory options can be selected for

improved efficiency at low operating frequency or

smaller solution size at high operating frequency.

Auto mode enables frequency foldback when

operating at light loads, allowing an unloaded current

consumption of only 7 μA (typical) and high light

load efficiency. Seamless transition between PWM

and PFM modes, along with very low MOSFET

ON resistances and an external bias input, provides

exceptional efficiency across the entire load range.
