SC411
SC411 is Synchronous Buck Pseudo-Fixed Frequency Power Supply Controller manufactured by SEMTECH.
Synchronous Buck Pseudo-Fixed Frequency Power Supply Controller
POWER MANAGEMENT Description
The SC411 is a constant on-time synchronous buck PWM controller in a space-saving MLPQ package intended for use in notebook puters and other battery operated portable devices. Features include high efficiency and a fast dynamic response with no minimum on-time. The excellent transient response means that SC411 based solutions will require less output capacitance than peting fixed frequency converters.
