Summary
CPU 5-Bit Synchronous Buck Controller Rev. 1/27/99
Description
The CS5157H is a 5-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 100ns response time to load transients. The CS5157H is designed to operate over a 4.25-20V range (VCC) using 12V to power the IC and 5V or 12Vas the main supply for conversion.
