Overview
CS5127 CS5127 Dual Output Nonsynchronous Buck Controller with Sync Function and Second Channel Enable 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.
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 circui...
