LT1725IS

Overview

The LT1725IS is a general-purpose isolated flyback controller manufactured by Analog Devices Inc. It operates within a switching frequency range of 50 kHz to 250 kHz and supports a maximum duty cycle of 90%. The device provides a single output with an output current capability of 500 mA and requires a supply voltage between 9.7 V and 22 V. It functions in boost/buck configurations and features soft-start and enable control characteristics. The component is housed in a 16-SOIC package, measuring 3.90 mm wide, and is designed for surface mount installation. It withstands operating temperatures from -40°C to +125°C TJ.

Feature Summary

General-purpose isolated flyback controller topology
Soft-start and enable control functionality
Boost/buck DC-DC switching capabilities
Wide operating temperature range support

Applications

Isolated power supply designs
General purpose flyback converter circuits
Industrial power management systems

Procurement Notes

Verify the specific suffix (PBF or TRPBF) against official Analog Devices documentation to confirm packaging type and RoHS compliance status. Ensure the selected variant matches the required tape-and-reel or tube configuration for manufacturing processes. Cross-reference the datasheet revision history for any recent package or specification updates before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a versatile isolated flyback solution with adjustable switching frequencies. Consider the 16-SOIC footprint for PCB layout constraints and verify thermal performance within the specified -40°C to +125°C junction temperature range. Confirm that the input voltage requirements align with the 9.7 V to 22 V operating window for stable controller operation.

Part Context

The LT1725 belongs to the LT1725 series of power management ICs under Analog Devices' portfolio. It is categorized as a DC-DC switching controller within the PMIC segment. This part serves as a core control element for designing efficient isolated power conversion stages, distinct from linear regulators or non-isolated switching controllers.
