LT1424IS8-5#TRPBF

Overview

The LT1424IS8-5#TRPBF is an isolated flyback switching regulator manufactured by Analog Devices Inc. It operates within a supply voltage range of 3 V to 20 V and delivers a fixed 5 V output at up to 400 mA. The device integrates a high-voltage oscillator with a switching frequency of 285 kHz, enabling compact transformer designs. Packaged in an SOIC-8 surface-mount format, it supports operation from -40°C to +125°C.

Feature Summary

Integrated high-voltage oscillator for simplified flyback converter design
Fixed 5 V output configuration eliminates external feedback components
Supports wide input voltage ranges suitable for various power sources

Applications

Isolated DC-DC conversion in industrial control systems
Power supplies for communication equipment requiring galvanic isolation
Battery-powered devices needing efficient step-down regulation

Procurement Notes

Verify the specific suffix IS8 against your bill of materials to ensure correct temperature grade and package variant. Confirm that the fixed 5 V output aligns with system requirements, as adjustable variants exist within the same family. Check current availability status due to potential supply constraints associated with this component series.

Selection Notes

Select this part when a fixed 5 V isolated output is required without external feedback networks. Consider the 285 kHz switching frequency for balancing efficiency and passive component size. Ensure the SOIC-8 thermal performance meets the application's heat dissipation needs under maximum load conditions.

Part Context

This component belongs to the LT1424 series of isolated switching regulators. It shares architectural similarities with other members like the LT1424CS8-5#TRPBF but differs in specified operating temperature ranges and manufacturing lot qualifications. The series targets applications requiring reliable, low-component-count isolated power solutions.
