The LT3748IMS#TRPBF from Analog Devices is a switching regulator controller specifically designed for the isolated flyback topology, capable of handling high power.
This controller drives an external N-channel power MOSFET and does not require a third winding or opto-isolator for regulation, sensing the isolated output voltage directly from the primary-side flyback waveform. It utilizes boundary mode operation to achieve a small magnetic solution without compromising load regulation. The operating frequency is determined by the load current and transformer magnetizing inductance.
Key electrical specifications include a wide input voltage range of 5V to 100V and an average gate drive source and sink current of 1.9A. Control features such as Enable and Soft Start are programmable. The device is suitable for applications requiring isolated power supplies, including telecom, automotive, and industrial power systems.
The LT3748IMS#TRPBF is available in a 16-lead MSOP package, surface-mounted. It operates within a junction temperature range of -40°C to 125°C.
