CS5151H CPU 4 Bit Nonsynchronous Buck Controller The CS5151H is a 4 bit nonsynchronous 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 CS5151H 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 .

CS5151H Features

* on board, 4

* bit DAC, short circuit protection, 1.0% output tolerance, VCC monitor, and programmable Soft Start capability. The CS5151H is upwards compatible with the 5

* bit CS5156H, allowing the mother board designer the capability of using either the CS5151H or the CS5156H with no c
