Description

The CS5127 is a fixed frequency dual output nonsynchronous buck controller. It contains circuitry for regulating two separate outputs. Each output channel contains a high gain error amplifier, a comparator and latch, and a totem-pole output driver capable of providing DC current of 100mA and peak current in excess of 0.5A.
