SC2643VX - Multi-Platform Multi-Phase PWM Controller

Description

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.

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 output voltage is accurately positioned according to the load current condition, and an internal temperature compensation technology further enhances the performance of voltage accuracy. The patented Co.

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. This architecture minimizes the core voltage ripple and the input current ripple, which leads to optimized voltage regulator design for power density, transient responses, and the thermal performances. To satisfy the highly dynamic nature of the modern microprocessors, the SC2643VX adopts peak current mode control topology which ensures wide control loop bandwidth and fast transient responses.
