Semtech SC2620

Beschreibung

The SC2620 is a constant frequency dual current-mode switching regulator with integrated 2.3A, 30V switches. Its switching frequency can be programmed up to 1.4MHz per channel. Due to the SC2620’s high frequency operation, small inductors and ceramic capacitors can be used, resulting in very compact power supplies. The two channels of the SC2620 operate at 180° out of phase for reduced input voltage ripples.
