NCP5162
General Purpose
Synchronous Buck Controller
The NCP5162 is a synchronous dual N鈥揅hannel buck controller
designed to provide unprecedented transient response for today鈥檚
demanding high鈥揹ensity, high鈥搒peed logic. It operates using a
proprietary control method which allows a 100 ns response time to
load transients. The NCP5162 is designed to operate over a 9鈥?6 V
range (V
CC
) using 12 V to power the IC and 5.0 V as the main supply
for conversion.
The NCP5162 is specifically designed for high performance core
logic. It includes the following features: 0.8% output tolerance, V
CC
monitor, and programmable Soft Start capability. The NCP5162 is
available in a 16 pin surface mount package.
