General Description

The SC1214 is a high speed, Combi-SenseTM, two-phase driver designed to drive high-side and low-side MOSFETs in two synchronous Buck converters.

The driver combined with Combi-Sense PWM controllers, such as Semtech SC2643VX or SC2643, provides a cost effective two-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 The detailed explanation of the technique can be found in the Applications Information section.

Key Features

  • are included for proper and safe operation. Timed latches and improved robustness are built into the housekeeping functions such as the Under Voltage Lockout and adaptive Shoot-through protection circuitry to prevent false triggering and to assure safe operation. The SC1214 is offered in a TSSOP-20 package. SC1214 Features u u u u u u u u u u u u High efficiency +12V gate drive voltage High peak drive current Adaptive non-overlapping gate drives provide shoot-through protection Support Combi-S.
