Synchronous step-down converter simplifies power conversion with up to 91% efficiency

April 9, 2026

The DCP3601NMR step-down converter from STMicroelectronics combines high efficiency with ultra-low standby power consumption, and comprehensive protection for battery-powered or mains-powered designs.

 

As a step-down converter, the DCP3601NMR provides up to 1A of output current from input sources between 3.3V and 36V. Part of the new DC+ converter family, from STMicroelectronics, the regulator emphasizes compact size for power designs.  

 

The DCP3601NMR switching frequency is fixed at 1MHz, allowing the use of small inductors and capacitors to minimize solution footprint. The converter’s wide VIN tolerance suits systems from battery packs to industrial 24V rails. Also included are output over-voltage limiting and a thermal shutdown (TSD) mechanism, so the converter can safely shut itself down if an abnormal event or excessive temperature is detected.
