Allegro added a 3A buck converter which uses valley current-mode control ideal for applications requiring high switching frequencies, high input voltages (9V-46V) and low output voltages (0.8V-15V).

The buck converter has emerged as a critical element in modern power electronics, offering highly efficient voltage step‐down conversion for a wide array of applications. Recent advances have focused ...

A high-efficiency, single-channel, synchronous-buck converter IC intended for point-of-load (POL) applications employs on-chip MOSFETs and proprietary mode control with adaptive on-time architecture.

This is a design idea of high efficiency constant current buck converter for LED lighting using LinkSwitch-TN. It operates in an input voltage ranging from 108 VAC to132 VAC and delivers an output of ...
