Description
The SC1486AITSTR is a single output, constant on-time synchronous-buck, pseudo-fixed frequency, PWM controller. It is designed for use in notebook computers and other battery-operated portable devices. This IC chip offers high efficiency, fast dynamic response, and no minimum on time. It features a reference input and a buffered REFOUT pin capable of sourcing 3mA. The SC1486AITSTR's excellent transient response reduces the required output capacitance compared to competing fixed-frequency converters.
