The LM63460-Q1 derives from a family of automotive synchronous buck DC/DC converters with excellent efficiency and ultra-low I Q. With integrated high-side and low-side MOSFETs, up to 6 A of output current is delivered over a wide input voltage range from 3 V to 36 V, with support for load-dump transients up to 42 V. The converter implements soft recovery from dropout to eliminate overshoot on the output.

The LM63460-Q1 incorporates numerous features for excellent EMI performance, including spread-spectrum frequency modulation, a low-EMI Enhanced HotRod QFN package that mitigates switch-node ringing, and a symmetrical pinout for ideal input capacitor placement. The switching frequency can be set between 200 kHz and 2.2 MHz to avoid sensitive frequency bands, while optimizing efficiency or design size based on the application requirements.

PFM mode enables frequency foldback during light-load operation, allowing an unloaded current consumption of only 7 µA (typical) and high light-load efficiency. A seamless transition between PWM and PFM modes, along with low MOSFET on-resistances and an external bias input, provides exceptional efficiency and thermal performance across the entire load range. The package has several NC pins between critical power pins, which improve the Failure Modes and Effects Analysis (FMEA) result.
