LT1425IS#PBF

Overview

The LT1425IS#PBF is an isolated flyback switching regulator manufactured by Analog Devices Inc. It operates within a 3 V to 20 V input voltage range and delivers up to 1 A output current through a single adjustable output channel. The device features a fixed switching frequency of 300 kHz and draws a typical quiescent current of 7 mA. Designed for industrial environments, it functions reliably between -40°C and +100°C. Packaged in a 16-pin SOIC N, this component integrates shutdown functionality and supports positive or negative isolated outputs.

Feature Summary

Provides galvanic isolation via flyback topology for safe signal and power separation
Supports adjustable output voltages with integrated shutdown control
Operates efficiently at a fixed 300 kHz switching frequency

Applications

Industrial control systems requiring isolated DC-DC conversion
Medical equipment needing safety-isolated power supplies
Telecommunications infrastructure utilizing isolated power rails

Procurement Notes

Verify the specific suffix IS#PBF against official Analog Devices documentation to confirm industrial temperature grading and lead-free compliance. Ensure the ordering part number matches the required package style and thermal specifications. Cross-reference datasheet revisions to validate pinout compatibility and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when an isolated flyback solution is required within a 3 V to 20 V input window. Consider the 1 A output capability and 300 kHz frequency for compact magnetic designs. Verify that the industrial temperature range meets environmental requirements. Compare against non-isolated alternatives if galvanic isolation is not strictly necessary for the application circuit.

Part Context

This part belongs to the LT1425 family of isolated flyback regulators from Analog Devices. It shares architectural similarities with other members like the LT1425CS#PBF but differs in temperature rating and packaging variants. The series is designed for applications demanding reliable isolated power conversion with minimal external component count.
