Active Clamp Synchronous Forward Controllers
The LT3752, LT3752‑1 and LT3753 are active clamp forward controllers that minimize external component count, solution size and cost. Two of these controllers, the LT3752 and LT3753, are designed for inputs up to 100V. The LT3752-1 is designed for applications with input voltages greater than 100V, suitable for HV car battery and offline isolated power supplies, industrial, automotive and military systems. The LT3752, LT3752-1 and LT3753 simplify the design and improve performance to isolated power supplies with a volt-second clamp architecture that produces accurate regulation. An integrated flyback controller can be used to produce a housekeeping supply, simplifying the magnetics. Additional features include programmable overcurrent protection, adjustable input undervoltage and overvoltage lockout, programmable turn-on current spike blanking and programmable delays between various gate signals.
