The LM27262 is a versatile synchronous buck voltage regulator controller designed according to the Intel VRD10 Specification. It’s a fixed-frequency voltage-mode control PWM with average current modulation of the reference voltage to achieve the desired output impedance.
Features
Compatible with “VRD10 Voltage Regulation Specification” for Intel Pentium 4 and Prescott Processors
Supports Intel SpeedStep™technology (Geyserville-III™), which enables real-time dynamic switching of the CPU core voltage and the CPU clock frequency
Uses external gate drivers (LM2724) for maximum ayout flexibility and noise immunity
Fixed frequency PWM architecture
Pin selectable internal or external voltage reference
0.5% core voltage set-point accuracy when using external voltage reference
