Overview
The LT8300ES5#TRPBF is a uPower isolated flyback converter IC from Analog Devices, housed in a TSOT-23-5 package. It supports input voltages up to 42V and provides an adjustable output voltage up to 65V with a maximum output current of 1.2A. The device operates at a fixed switching frequency of 10.6kHz and features a low quiescent current of 350µA. Designed for surface mount installation, it functions within a minimum operating temperature of -40°C.
Feature Summary
- Integrated high-voltage switch enables compact isolated flyback designs without external optocouplers
- Low quiescent current consumption supports battery-powered applications requiring extended standby life
- Fixed low-frequency operation minimizes electromagnetic interference in noise-sensitive environments
Applications
- Isolated DC-DC conversion for industrial sensor interfaces
- Power supply stages in portable medical instrumentation
- Auxiliary power generation in automotive control modules
Procurement Notes
Verify component authenticity through authorized distribution channels due to limited availability status. Confirm RoHS compliance and manufacturing date codes against current Analog Devices specifications. Ensure storage conditions maintain moisture sensitivity level integrity prior to reflow soldering processes.
Selection Notes
Select this component when designing small-footprint isolated converters requiring minimal external components. The TSOT-23-5 package suits space-constrained layouts. Evaluate thermal performance under maximum load conditions given the small outline transistor package constraints.
Part Context
Part of the LT8300 family of uPower isolated flyback controllers. Shares architectural similarities with LT8301 and LT8302 series but offers specific voltage and current ratings tailored for low-power isolated applications. Compatible with standard evaluation boards like DC1825A for design verification.
Replacement Considerations
LT8300ES5#PBF serves as the tube-packaged equivalent. LT8301ES5#TRPBF offers similar functionality with potentially different electrical characteristics. Verify pin compatibility and thermal requirements before substitution.
