General Description

The LM27402 is a voltage-mode, synchronous, DC/DC step-down controller with lossless inductor DCR current sensing capability.

Sensing the inductor current eliminates the need to add resistive powertrain elements, which increases overall efficiency and facilitates accurate, continuous current sensing.

A 0.6-V ±1% voltage reference enables high accuracy and low voltage capability at the output.
