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.
