Description

The SC453 IC is a single chip high-performance Hysteretic PWM controller. With its integrated SmartDriver?, it pow ers advanced graphics and core processors. It provides sleep mode and boot voltage support. Automatic power save is present to prevent negative current flow in the

low-side FET during light loading conditions saving even more power. The high side driver initially turns on with a weak drive to reduce ringing, EMI, and capacitive turn-on of the low side.
