This page is updated frequently with new Synchronous Rectifier Controller-related patent applications.

Efficient power supply voltage regulation for synchronous rectifier controller
A flyback converter is provided with a synchronous rectifier (sr) controller including a pulse linear regulator (plr) charging path and an ldo charging path. The sr controller is configured to monitor the switching period and/or duty cycle of a power switch in the flyback converter to select between the plr and ldo charging paths..
Dialog Semiconductor Inc.


Method and synchronous rectifier
A synchronous rectifier controller includes an exception timer, one or more blanking timers, and control logic. The control logic may detect a beginning of a conduction phase using a current sense signal.
Semiconductor Components Industries, Llc


Adaptive synchronous rectifier control
A switching power converter may include a power switch coupled to a primary winding of a transformer, and a primary controller configured to turn on and off the power switch, a synchronous rectifier switch coupled to a secondary winding of a transformer, and a synchronous rectifier controller configured to turn on and off the synchronous rectifier switch. The synchronous rectifier controller may monitor a voltage across the synchronous rectifier switch.
Dialog Semiconductor Inc.


Dead time compensation for synchronous rectifiers in adaptive output powers
A synchronous rectifier controller for an adaptive output power converter is provided. The synchronous rectifier controller includes a voltage detection circuit, a threshold generation circuit, and a driver.
Fairchild (taiwan) Corporation
