Product Details

LM61495QRPHRQ1 is a 10-A automotive synchronous buck converter supplied in a 16-pin, wettable-flank RPH VQFN-HR package for high-current point-of-load rails.

Its 3-to-36-V input range accommodates vehicle-derived supply variation, while the integrated switches remove the need to size a separate high-side and low-side MOSFET pair.

A programmable 200-kHz-to-2.2-MHz frequency range lets the designer balance magnetic size, switching loss and placement relative to sensitive radio bands.

Pin-selectable spread spectrum and adjustable switch-node rise time help control emissions at the source rather than relying entirely on later filtering and shielding.

The selectable constant-frequency or pulse-frequency-modulation light-load mode and filtered reset output provide system-level choices for idle efficiency and downstream power sequencing.
