LT1425CS#TRPBF

Overview

The LT1425CS#TRPBF is an isolated flyback switching voltage 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 285 kHz and maintains a typical quiescent current of 7 mA. Designed for surface-mount applications, it utilizes a 16-lead SOIC package. The component supports shutdown functionality and functions reliably across an operating temperature range from 0°C to +100°C.

Feature Summary

Provides galvanic isolation via integrated flyback topology
Supports adjustable output voltage configuration
Includes shutdown control capability for power management

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when sourcing. Confirm that the CS variant corresponds to the commercial temperature grade. Ensure compatibility with 16-lead SOIC footprints during PCB layout. Cross-reference official datasheets for pinout definitions and thermal requirements before integration.

Selection Notes

Select this component when isolated flyback regulation is required with adjustable output capabilities. Consider the 285 kHz switching frequency for EMI constraints. Evaluate the 1 A output limit against load requirements. Verify that the 3 V to 20 V input range matches the source supply. Check thermal performance within the 0°C to +100°C operational envelope.

Part Context

This part belongs to the LT1425 series of isolated flyback regulators. It shares functional similarities with other members like the LT1424 but differs in output specifications and package options. The CS designation indicates a commercial temperature range variant housed in a standard SOIC package, distinct from wider temperature or smaller package alternatives.
