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. A common oscillator controls switching for both channels, and a sync lead is provided to allow parallel supply operation or shifting of the switching noise spectrum. An on-chip 5V reference is capable of providing as much as 10mA of current for external circuitry. The CS5127 also contains two undervoltage lockout
