Secondary Side Controllers
Analog Devices’ synchronous secondary side controllers enable higher efficiency solutions, allowing higher power levels and smaller solutions size. Unlike prior solutions that used a signal transformer driven from the primary side to control the synchronous rectifier, our solutions sense the drain-to-source voltage of the MOSFET for activation. This technique not only eliminates a transformer, but allows the secondary side controller to work with ADI’s growing line of no-optocoupler products required for output voltage feedback boundary conduction mode (BCM)/critical conduction mode (CrCM) flyback converters, which makes it highly versatile for many types of applications.
