The MlC24046 is a pin-programmable, high-efficiency.wide input range,5A synchronous step-down regulator.The MlC24046 is perfectly suited for multiple-voltage railapplication environments typically found in computing andtelecommunication systems. lt can be programmed by pinstrapping various parameters,such as output voltage,switching frequency,and current-limit values. The pin-selectable switching frequency,valley-current modecontrol technique,high-performance error amplifier, andexternal compensation allowfor the best trade-offsbetween high efficiency and the smallest possible solution size.
