NCP5220A Datasheet 3-in-1 Pwm Dual Buck And Linear Power Controller

Manufacturer: onsemi

Overview: NCP5220A 3−in−1 PWM Dual Buck and Linear Power Controller The NCP5220A 3−in−1 PWM Dual Buck and Linear Power Controller, is a plete power solution for MCH and DDR memory. This IC bines the efficiency of PWM controllers for the VDDQ supply and the MCH core supply voltage with the simplicity of linear regulator for the VTT termination voltage. This IC contains two synchronous PWM buck controllers for driving four external N−Ch FETs to form the DDR memory supply voltage (VDDQ) and the MCH regulator. The DDR memory termination regulator (VTT) is designed to track at half of the reference voltage with sourcing and sinking current.
