LM2743 N-Channel FET Synchronous Buck Regulator Controller for Conversion from 3.
3V
General Description
The LM2743 is a high-speed, N-Channel synchronous buck regulator controller with a 2%, 0.
6V feedback reference
voltage intended to make down conversion from 3.
3V to as low as 0.
6V easy.
A fixed-frequency
voltage-mode PWM control architecture is used, that is adjustable from 50kHz to 2MHz through an external resistor.
This wide range of PWM frequencies gives the power supply designer the flexibility to make tradeoffs among component size, cost, noise and efficiency.
The power
MOSFETs can run on ...
