LM27262 Overview
SNVS262C MAY 2004 REVISED SEPTEMBER 2011 LM27262 Intel CPU Core Voltage Regulator Controller for VRD10 patible PCs Check for Samples:.
LM27262 Key Features
- 234 patible 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 Volt
- Uses External Gate Drivers (LM2724) for Maximum Layout 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
- 0.9% Accurate Internal Bandgap Reference
- 2-, 3- or 4-Phase Operation
- Out-of-Phase Switching Reduces Input Ripple Current, Thereby Minimizing Input Capacitor Requirements
- VID-Code Programmable Output Voltage Range of 0.8375V through 1.6000V
LM27262 Applications
- Server and Desktop puter CPU Core Power Supplies Requiring a 2, 3- or 4-Phase Voltage Regulator Delivering up to 100A
