Overview
CS5132H CS5132H DEVICE NOT RECOMMENDEDARCHFORIVNEWE DESIGN Dual Output CPU Buck Controller Description Features The CS5132H is a dual output CPU power supply controller.
It contains a synchronous dual NFET buck controller utilizing the V2TM control method to achieve the fastest possible transient response and best overall regulation.
The CS5132H also contains a second nonsynchronous NFET buck controller.
These synchronous and nonsynchronous buck regulators are designed to power the core and I/O logic of the latest high performance CPUs.
The CS5132H incorporates many additional features required to ensure the proper operation and protection of the CPU and power system.
The CS5132H dual output provides the industry’s most highly integrated solution, minimizing external component count, total solution size, and cost.
The CS5132H is specifically designed to power Intel’s Pentium® II processor and includes the following features: 5-bit DAC and fixed 1.
23V reference, Power-Good output, hiccup mode overcurrent protection, adaptive voltage positioning, and overvoltage protection.
The CS5132H will operate over an 8.
4V to 20V range and is available in 24 lead surface mount package.
