LM27402 Datasheet (Texas Instruments) - High-Performance Synchronous Buck Controller

LM27402, High-Performance Synchronous Buck Controller

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
