Part Number LM2743
Description N-Channel FET Synchronous Buck Regulator Controller
Feature LM2743 N-Channel FET Synchronous Buck Re gulator Controller for Conversion from 3.
3V April 2004 LM2743 N-Channel FET Synchronous Buck Regulator Controller f or Conversion from 3.
3V General Descrip tion The LM2743 is a high-speed, N-Chan nel synchronous buck regulator controll er with a 2%, 0.
6V feedback reference v oltage intended to make down conversion from 3.
3V to as low as 0.
6V easy.
A fi xed-frequency voltage-mode PWM control architecture is used, that is adjustabl e from 50kHz to 2MHz through an externa l resistor.
This wide range of PWM freq uencies gives the power supply designer the flexibili .
