Linear Technology was a premier American semiconductor company specializing in high-performance analog integrated circuits. Founded in 1981, the company was acquired by Analog Devices (ADI) in 2017 to create an industry powerhouse.
Linear Technology is now fully integrated into Analog Devices. Through this combination, engineers and customers have access to an expanded portfolio that includes power management, data conversion, signal conditioning, and RF interface.

Product Overview

LT®3575 is a monolithic switching regulator specifically designed for the isolated flyback topology. No third winding or optoisolator is required for regulation. The part senses the isolated output voltage directly from the primary side flyback waveform. It operates with input supply voltages from 3V to 40V, and can deliver output power up to 14W with no external power switch. This utilizes boundary mode operation to provide a small magnetic solution with improved load regulation. The output voltage is easily set with two external resistors and the transformer turns ratio. Application includes industrial, automotive and medical isolated, power supplies.

  • Boundary mode operation
  • No transformer third winding or optoisolator required for regulation
  • Improved primary-side winding feedback load regulation
  • VOUT set with two external resistors
  • BIAS pin for internal bias supply and power NPN driver
  • Programmable soft-start, programmable power switch current limit
  • Input voltage range from 3 to 40V (TA = 25°C, VIN = 12V)
  • 16-lead plastic TSSOP package
  • Temperature rating range from -40°C to 125°C

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large manufacturing Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’, they are however pristine, stored with us sealed in original manufacturers packaging (taped and reeled), the photographs are representative of their excellent condition, being of some of our actual stock, and, as with all our products they come with a full guarantee. 

If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
