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 ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...
