LM2636 5-Bit Programmable Synchronous Buck Regulator Controller

The LM2636 is a high speed controller designed specifically for use in synchronous DC/DC buck converters for advance d microprocessors. A 5-bit DAC accepts the VID code directly from the CPU and adjusts the output voltage from 1.3V to 3.5V. It provides the power good, over-voltage protection, and ou.

LM2636 Features

* as required by Intel VRM specifications. Current limiting is achieved by monitoring the voltage drop across the rDS_ON of the high side MOSFET, which eliminates an expensive current sense resistor. The LM2636 employs a fixed-frequency voltage mode PWM architecture. To provide a faster response to a
