Linear Technology Corporation announces the LT8309, a flyback secondary-side synchronous rectifier driver that replaces the output diode with a MOSFET, allowing up to 10A output current without the use of a heat sink. The maximum output current of a flyback power supply has been limited by the power loss and heat generated from the output diode when no heat sink is used. The LT8309 replaces the diode forward voltage drop with the RDS(ON) of an external N-channel MOSFET, thereby reducing the power loss, increasing converter efficiency and easing the thermal design.
