SC1486AITSTRT.TR - Brand New SEMTECH IC Chips
-
Description
The SC1486AITSTRT.TR 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 controller has a reference input and a buffered REFOUT pin capable of sourcing 3mA. This model offers excellent transient response, reducing the required output capacitance compared to competing fixed frequency converters.
