4−In−1 PWM Buck and

Tri−Linear Power Controller

The NCP5209 4−In−1 PWM Buck and Tri−Linear Power Controller

is a complete ACPI compliant power solution for MCH and DDR

memory. This IC combines the high efficiency of a PWM controller

for the VDDQ supply with the simplicity of linear regulator for the

VTT termination voltage as well as the MCH core supply voltage.

This IC contains a synchronous PWM buck controller for driving

two external N−Ch FETs to form the DDR memory supply voltage

(VDDQ). The DDR memory termination regulator (VTT) is designed

to track at the half of reference voltage while sourcing and sinking

current. The two linear regulator controllers driving two external

N−Ch FETs are cascaded to produce the MCH core voltage (VMCH).

Protective features include, soft−start circuitry, undervoltage

monitoring of 5VDUAL, 5VATX and 12VATX, and thermal

shutdown. The device is housed in a thermal enhanced space−saving

QFN−20 package.
