LT8303HS5#TRPBF

Overview

The LT8303HS5#TRPBF is a high-efficiency, isolated flyback DC/DC converter from Analog Devices. It operates with an input voltage range of 2.7V to 42V and delivers up to 450mA output current. The device features adjustable output voltage and integrates synchronous rectification for improved performance. It functions within a temperature range of -40°C to +150°C TJ. Packaged in a TSOT-23-5 surface-mount case, it supports shutdown functionality and includes internal soft-start capabilities.

Feature Summary

Integrates synchronous rectification to enhance conversion efficiency
Supports wide input voltage ranges up to 42V
Includes internal soft-start to limit inrush current
Features compact TSOT-23-5 packaging for space-constrained designs

Applications

Industrial control systems requiring isolated power
Battery-powered equipment needing efficient step-down conversion
Automotive electronics operating in harsh thermal environments
Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix HS5 against official Analog Devices documentation to confirm temperature grade and material compliance. Ensure the TRPBF designation matches the required reel packaging format for automated assembly processes. Cross-reference the full part number with current distributor availability lists as supply status may vary by region.

Selection Notes

Select this component when high efficiency in isolated flyback topologies is required without external optocouplers. The integrated synchronous rectifier reduces conduction losses compared to traditional diode-based solutions. Consider the TSOT-23-5 package size for applications with strict board area limitations. Validate that the 450mA output capability meets the load requirements of the target circuit design.

Part Context

This part belongs to the LT8303 family of isolated flyback converters designed for high-density power applications. It shares architectural similarities with other members like the LT8300 and LT8301 but offers specific current and voltage characteristics tailored for mid-power isolated conversions. The series emphasizes simplicity by eliminating the need for auxiliary windings or optocouplers.
