LTC3725 - Single-Switch Forward Controller And Gate Driver

The LTC3725 is a controller for a single-switch forward converter and includes an on-chip Gate driver. For secondary-side control, combine the LTC3725 with the LTC3706 PolyPhase secondary-side synchronous forward controller to create a complete forward converter using a minimum of Discrete parts. A proprietary scheme is used to multiplex Gate drive signals across the isolation barrier through a tiny pulse transformer. The on-chip Rectifier and the same pulse transformer provide Gate drive bias power.
Alternatively, the LTC3725 CAN be used as a standalone voltage mode controller in a primary-side control architecture with optoisolator feedback. Voltage feedforward provides excellent line regulation and transient response.
