NCP5222: Synchronous Buck Controller, 2-Channel, 2-Phase
The NCP5222 is a fast transient response and high efficiency dual channel two phase buck controller with built in gate drivers. It provides multi functional power solutions for notebook power systems. 180 deg interleaved operation between the two channels and or phases has a capabiliyt of reducing cost of the common input capacitors and improving noise immunity. the interleaved operation also can reduce cost of the output capacitors with the two phase configuration. Input supply voltage feedforward control is employed to deal with wide input voltage range. On line porgrammable and automatic power saving control ensures high efficiency over entire load range. Fast transient response reduces requirement on the output filters. In the dual channel operation mode, the two ouput power rails are regulated individually. In the two phase operation mode, the two output power rails are connected together by an external switch and current sharing control is enabled to balance power delivery between phases.
