The regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to of load current from an input up to 60 V. Tolerance goes up to 65 V, easing input surge protection.

The use peak-current-mode control to provide exceptional efficiency and output accuracy in a small solution size. Seamless transition between PWM and PFM modes, along with very low MOSFET ON resistances and an external bias input, ensures exceptional efficiency across the entire load range.

This device requires few external components and has a pinout designed for simple PCB layout with best-in-class EMI and thermal performance. The small solution size and feature set of the LM76005 are designed to simplify the implementation for a wide range of end equipment.

The device is available in the WQFN 30-pin leadless package with wettable flanks.
