LT1425CS#PBF

Overview

The LT1425CS#PBF 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 utilizes a fixed 285 kHz switching frequency and maintains a typical quiescent current of 7 mA. Designed for surface-mount installation, it is housed in a 16-lead SOIC package. The component supports a shutdown function and functions reliably across an operating temperature range from 0°C to +100°C.

Feature Summary

Provides galvanic isolation via flyback topology for safe power conversion
Integrates internal oscillator for fixed-frequency operation without external timing components
Includes shutdown capability for system power management

Applications

Isolated DC/DC converter designs
Industrial control systems requiring regulated isolated power
Telecommunications equipment power supplies

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before procurement. Confirm the SOIC-16 package dimensions match your PCB footprint requirements. Ensure the input voltage range aligns with your source supply. Check for any regional distribution restrictions or limited availability status directly with authorized suppliers.

Selection Notes

Select this component when an isolated output is required from a low-voltage input source. The 1 A switch current rating suits moderate power applications. Consider the 285 kHz frequency for balancing efficiency and passive component size. Verify thermal performance within the specified 0°C to +100°C junction temperature range for your enclosure design.

Part Context

This part belongs to the LT1425 series of isolated flyback regulators. It serves as a complete solution for generating isolated voltages from unregulated or regulated inputs. The CS#PBF designation indicates commercial temperature grade and tube packaging. It replaces older discrete solutions by integrating control logic and power switching elements.
