Description
The SC1480AITSTRT is a single output, constant on-time synchronous-buck, pseudo-fixed frequency, PWM controller intended for use in notebook computers and other battery-operated portable devices. It features high efficiency, fast dynamic response, and no minimum on time. The SC1480AITSTRT also includes a reference input and a buffered REFOUT pin capable of sourcing 3mA. This controller's excellent transient response means that solutions based on the SC1480AITSTRT will require less output capacitance than competing fixed frequency converters.
