SC2647
Product inactive. Information on this page is for reference only.
The SC2647 provides microprocessor core voltage regulation solution up to 4 paralleled PWM channels. The solution can also be configured as 2, 3, or 4-phase form. Multi-phase buck regulator utilizes the phase-shift timing control to allow interleaved switching of the power switches.
