Overview
The LT8300HS5#TRMPBF is a micropower isolated flyback converter featuring an integrated 140V, 260mA switch. It supports input voltages up to 100V and operates within a temperature range of -40°C to +125°C. The device utilizes a TSOT-23-5 package for surface-mount installation. Key electrical specifications include a quiescent current of 170µA and a switching frequency of 100kHz. It provides adjustable output voltage control via an external resistor divider.
Feature Summary
- Integrates a high-voltage 140V switch capable of delivering 260mA output current
- Supports wide input voltage ranges up to 100V for flexible power supply designs
- Features micropower operation with low quiescent current consumption
- Provides galvanic isolation suitable for flyback converter topologies
Applications
- Isolated DC/DC conversion in industrial instrumentation
- Power supplies for sensor interfaces requiring galvanic isolation
- Battery-operated devices needing efficient step-up or inverted voltage generation
- Medical equipment power stages with strict isolation requirements
Procurement Notes
Verify the specific suffix HS5 against official Analog Devices documentation to confirm the extended temperature grade and commercial-grade variant distinctions. Confirm availability status as distribution channels may list limited stock or end-of-life statuses. Ensure the TSOT-23-5 package dimensions match your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when designing isolated flyback converters requiring high input voltage tolerance up to 100V. The integrated 140V switch eliminates the need for external high-voltage MOSFETs, simplifying the bill of materials. Consider the 260mA current limit for load requirements and ensure thermal management aligns with the TSOT-23-5 package constraints in enclosed environments.
Part Context
This part belongs to the LT8300 family of micropower isolated flyback converters from Analog Devices. It shares architectural similarities with other members like the LT8300ES5 but differs in temperature rating and specific electrical characteristics defined by the HS5 suffix. The series targets applications demanding compact, high-voltage isolated power solutions with minimal external component count.
Replacement Considerations
LT8300ES5#TRMPBF: Lower temperature grade (-40°C to +85°C). LT8300IS5#TRMPBF: Industrial temperature grade (-40°C to +125°C) with potentially different electrical tolerances.
