LT1424IS8-9#TRPBF

Overview

The LT1424IS8-9#TRPBF is an isolated flyback switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3 V to 20 V and provides a fixed output voltage of 9 V at up to 200 mA. The device utilizes a SOIC-8 package and functions at a switching frequency of 285 kHz. It features a shutdown capability and maintains a quiescent current of 7 mA. The component supports operation across a temperature range from -40 °C to +125 °C.

Feature Summary

Integrated isolated flyback topology for galvanic isolation
Fixed 9 V output configuration with high current capability
Shutdown pin functionality for power management

Applications

Industrial control systems requiring isolated power rails
Medical equipment needing safety isolation
Telecommunications infrastructure power supplies

Procurement Notes

Verify the exact suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the IS8 designation matches the required industrial temperature grade and SOIC-8 footprint. Ensure compatibility with existing transformer designs specified for the 285 kHz switching frequency. Validate that the 9 V fixed output aligns with system requirements without additional regulation stages.

Selection Notes

Select this component when a compact, isolated DC-DC solution is needed with minimal external components. The fixed 9 V output simplifies design compared to adjustable regulators. Consider the 200 mA output current limit against load demands. The wide input range accommodates various supply sources common in industrial environments.

Part Context

This part belongs to the LT1424 series of isolated flyback regulators. These devices integrate the controller and primary switch into a single package. The series offers alternatives with different fixed output voltages, such as 5 V or 12 V variants, sharing similar operational characteristics and package styles.
