SC2643VX Datasheet (Semtech Corporation) - Multi-Platform Multi-Phase PWM Controller

SC2643VX, Multi-Platform Multi-Phase PWM Controller

The SC2643VX provides a solution for microprocessor core voltage regulation with up to 4 paralleled PWM channels.

The solution can also be configured as 2, 3, or 4-phase form.

This multi-phase buck regulator utilizes the phaseshift timing control to allow interleaved switching of the power switches.

SC2643VX Features

* of the SC2643VX is its voltage regulation accuracy. Not only does it provide better than 0.5% set point accuracy, but also the accuracy to be fully compliant with stringent load line slope specifications mandated by the modern microprocessors. Lossless output current sensing ensures the regulator ou
