LM62440BPPQRJRRQ1 TI Switching Voltage Regulators Automotive 3-V to 36-V, 4-A, low-noise synchronous step-down converter
1.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
