NCP5220A Description
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...
