Overview
LM2636 5-Bit Programmable Synchronous Buck Regulator Controller October 1999 LM2636 5-Bit Programmable Synchronous Buck Regulator Controller General Description 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 output enable 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...
