Overview
The LT8300IS5#WTRPBF is an automotive-grade, isolated flyback switching regulator IC manufactured by Analog Devices Inc. It operates within a 6V to 100V input voltage range and supports adjustable output voltages up to 150V. The device delivers a maximum switch current of 260mA with a switching frequency range of 7.5kHz to 750kHz. Packaged in a TSOT-23-5 surface-mount format, it functions as a buck converter topology suitable for applications requiring positive or negative isolated outputs.
Feature Summary
- Provides galvanic isolation for generating positive or negative output voltages without requiring external optocouplers.
- Capable of operating with high input voltages up to 100V, enabling direct conversion from industrial power rails.
- Features adjustable switching frequencies to optimize efficiency and minimize electromagnetic interference in compact designs.
Applications
- Industrial sensor interfaces requiring isolated signal transmission
- Medical equipment needing safety-isolated power supplies
- Automotive electronics demanding AEC-Q100 qualified components
Procurement Notes
Verify the specific suffix WTRPBF confirms the tape-and-reel packaging configuration and lead-free status. Confirm that the IS5 grade meets the required automotive temperature specifications for your target environment. Ensure compatibility with the intended PCB footprint for the TSOT-23-5 package before finalizing procurement orders.
Selection Notes
Select this component when a small form factor is critical for isolated power generation. The wide input voltage range allows flexibility in sourcing power from various bus architectures. Consider the 260mA output limit to ensure it meets the load requirements of the downstream circuitry without exceeding thermal limits.
Part Context
This part belongs to the LT8300 family of no-opto isolated flyback converters. It shares architectural similarities with other members like the LT8301 and LT8302 but is distinguished by its specific current rating and TSOT-23-5 packaging. The family focuses on simplifying isolated power supply designs by integrating control logic directly into the controller.
Replacement Considerations
LT8300ES5#WTRPBF serves as a commercial grade alternative within the same package, though it lacks automotive qualification. Other LT8300 variants may offer different pinouts or performance characteristics; verify datasheet compatibility before substitution.
