General Description

The SC1211 is a high speed, Combi-SenseTM, dual output driver designed to drive high-side and low-side MOSFETs in a synchronous Buck converter.

These drivers combined with Combi-Sense PWM controllers, such as Semtech SC2643VX or SC2643, provide a cost effective multi-phase voltage regulator for advanced microprocessors The Combi-SenseTM is a technique to sense the inductor current for peak current mode control of voltage regulator without using sensing resistor.

It provides the following advantages: - No costly precision sensing resistor - Lossless current sensing - High level noise free signal - Fast response - Suitable for wide range of duty cycle - Only two small signal components (third optional) The detailed explanation of the technique can be found in the Applications Information section.
