Overview
The LT3574IMS#TRPBF is a monolithic isolated flyback converter IC from Analog Devices Inc., designed for low input voltage applications. It operates with an input voltage range of 3V to 40V and provides a single output capable of delivering up to 650mA. The device integrates the high-side switch, eliminating the need for external opto-couplers or transformer feedback windings. It supports non-inverting, inverting, step-up, and step-down topologies within a 16-pin MSOP package. The operating temperature range extends from -40°C to 85°C.
Feature Summary
- Integrates high-side switch for simplified isolated flyback designs without opto-couplers
- Supports multiple conversion topologies including non-inverting, inverting, step-up, and step-down
- Operates over a wide input voltage range suitable for low voltage sources
Applications
- Low input voltage isolated power supplies
- ±12V isolated flyback converters
- 5V isolated flyback converters
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. (formerly Linear Technology). Ensure the part number matches the required 16-lead MSOP package configuration. Cross-reference the datasheet for thermal performance requirements under your specific load conditions.
Selection Notes
Select this component for designs requiring galvanic isolation without the complexity of traditional opto-isolated feedback loops. It is suitable for applications needing a compact solution for converting low DC voltages to isolated rails. Consider the 650mA output limit and input voltage range against your system requirements before finalizing the design.
Part Context
This part belongs to the LT3574 family of isolated flyback converters. It is manufactured by Analog Devices Inc. The IMS#TRPBF designation specifies the MSOP-16 package and tape-and-reel shipping format. It serves as a drop-in replacement for discrete solutions requiring isolation in space-constrained environments.
Replacement Considerations
LT3574IMS#PBF is the tube-packaged equivalent of the same functional device. Verify pinout compatibility if substituting between reel and tube formats. No other direct substitutes are confirmed in public documentation.
