The NCP5222, a fast-transient-response and high-efficiency dual-channel / two-phase buck controller with built-in gate drivers, provides multifunctional power solutions for notebook power system. 180 interleaved operation between the two channels / phases has a capability 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 programmable 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 output 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. |
