LT8309
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
- Works with DCM and BCM/CrCM Conduction Mode Flyback Topologies
- VCC: 4.5V to 40V
- Supports Up to 150V MOSFETs
- 26ns Turn-Off Propagation Delay
- Accurate Minimum On and Off Timers for Reliable Operation
- Adjustable and Accurate Trip Point: +5mV to -30mV
- 1Ω Gate Driver Pull-Down
- SOT-23 5-Lead Package
