CS5150H CPU 4 Bit Synchronous Buck Controller The CS5150H is a 4 bit synchronous dual N Channel buck controller.

It is designed to provide unprecedented transient response for today’s demanding high density, high speed logic.

The regulator operates using a proprietary control method, which allows a 100 ns response time to load transients.

The CS5150H is designed to operate over a 4.25 20 V range (VCC) using 12 V to power the IC and 5.0 V or 12 V a
