NCP5215 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 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. Features • Wide Input Voltage Range: 4.
