NCP5215

Dual Synchronous Buck Controller for Notebook

Overview

The NCP5215, a high-efficiency and fast-transient-response dual-channel buck controller, provides a multifunctional power solution for notebook power system. 180^o 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.
