NCP5214 Notebook DDR Power Controller

Pin Symbol Description 1 VDDQEN VDDQ regulator enable input. High to enable. 2 VTTEN VTT regulator enable input. High to enable. 3 FPWM Forced PWM enable input. Low to enable forced PWM mode and disable power *saving mode. 4 SS VDDQ Soft *start capacitor connection to ground.

NCP5214 2 in 1 Notebook DDR Power Controller The NCP5214 2 in 1 Notebook DDR Power Controller is specifically designed as a total power solution for notebook DDR memory system. This IC combines the efficiency of a PWM controller for the VDDQ supply with the simplicity of linear regulators for the VTT termination voltage and the buffered low noise reference. This IC contains a synchronous PWM buck controller for driving two external NFETs to form the DDR memory su.
