LT1425IS#TRPBF

Overview

The LT1425IS#TRPBF is an isolated flyback switching regulator manufactured by Analog Devices Inc., designed for high-efficiency power conversion in compact applications. It operates with an input voltage range of 3 V to 20 V and delivers a maximum output current of 1 A. The device features a fixed switching frequency of 285 kHz and maintains a typical quiescent current of 7 mA. It provides adjustable single output capability within a 16-pin SOIC package, supporting industrial temperature ranges from -40°C to +100°C.

Feature Summary

Integrated isolated flyback topology for galvanic isolation
Adjustable output voltage configuration
Built-in shutdown control functionality

Applications

Industrial control systems requiring isolated power supplies
Telecommunications equipment power distribution
Medical instrumentation power stages

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the IS grade matches required industrial temperature specifications for your design environment.

Selection Notes

Select this component when isolated flyback regulation is required with low standby current consumption. The 285 kHz frequency allows for smaller magnetic components compared to lower-frequency alternatives. Verify that the 1 A output current meets load requirements while accounting for transformer efficiency losses in the final design.

Part Context

This part belongs to the LT1425 series of isolated flyback regulators from Analog Devices. It shares core architecture with other variants in the family but differs in packaging and temperature grading. The IS designation specifically denotes industrial temperature range operation suitable for demanding environments.
