The LT1725CGN is a monolithic switching regulator controller specifically designed for the isolated flyback topology. It drives the gate of an external MOSFET and is generally powered from a third transformer winding, allowing for application input voltage limited only by external power path components. The third transformer winding also provides output voltage feedback information, eliminating the need for an optoisolator.
Key electrical specifications include a VCC supply voltage of up to 22V, an ISENSE pin voltage limit of 2V, and a feedback pin current limit of ±2mA. The switching frequency can be set from 50kHz to 250kHz using an external capacitor.
This controller is available in a 16-pin SSOP package. Its design allows for accurate regulation without user trims and maintains regulation well into discontinuous mode. Optional features include load compensation and undervoltage lockout.
The LT1725CGN is suitable for applications such as telecom isolated converters, offline isolated power supplies, and instrumentation power supplies.
