Datasheet Summary
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. 180o interleaved operation function between the two channels has capabilities of reducing the mon 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)...
