LT8309 Overview
Description
The LT®8309 is a secondary-side synchronous rectifier driver that replaces the output rectifier diode in a flyback topology. By replacing the diode with a N-channel MOSFET, applications are no longer restricted by the heat constraints of the output diode.
Key Features
- VCC: 4.5V to 40V
- Supports Up to 150V MOSFETs n 26ns Turn-Off Propagation Delay
- Accurate Minimum On and Off Timers for Reliable Operation
- Adjustable and Accurate Trip Point: +5mV to –30mV n 1Ω Gate Driver Pull-Down
- SOT-23 5-Lead Package
