com CS5161, CS5161H CPU 5−Bit Synchronous Buck Controller The CS5161/5161H are 5−bit synchronous dual N−Channel buck controllers designed to provide unprecedented transient response for today’s demanding high−density, high−speed logic.
They operate using a proprietary control method which allows a 100 ns response time to load transients.
The CS5161 is designed to operate over a 9−16 V range (VCC) using 12 V to power the IC and 5.
0 V as the main supply for conversion.
The CS5161H operates from a 12 V input as the main supply for conversion using a discrete charge pump circuit to provide up to 20 V for VCC2 and high side gate drive.
The CS5161/5161H are specifically designed to power Pentium® III processors and other high performance core logic.
They include the following features: on board 5−bit DAC, short circuit protection, 1.
0% output tolerance, VCC monitor, and programmable Soft Start capability.
The CS5161/5161H are available in 16 pin surface mount packages.
