LM2635 5-Bit Programmable Synchronous Buck Regulator Controller

The LM2635 is a high speed controller designed specifically for use in synchronous DC/DC buck converters for the Pentium™ II or Deschutes microprocessor. A 5-bit DAC accepts the VID code directly from the CPU and adjusts the output voltage from 1.8V to 3.5V. It provides the power good, over-voltage .

LM2635 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 LM2635 employs a fixed-frequency voltage mode PWM architecture. To provide a faster response to a
