Dual Synchronous Buck

Controller for Notebook

Power System

The NCP5215, a high−efficiency and fast−transient−response

dual−channel buck controller, provides a multifunctional power

solution for notebook power system. 180 interleaved operation

function between the two channels has capabilities of reducing the

common input capacitor requirement and improving noise immunity.

Adaptive−Voltage−Positioning (AVP) control reduces the

requirement of output filter capacitors. Programmable power−saving

operation ensures high efficiency over entire load range. Input

feedforward voltage−mode control is employed to deal with wide

input voltage range. Transient−Response−Enhancement (TRE)

control for the both channels enables fast transient response.
