LT3575IFE#PBF

Overview

The LT3575IFE#PBF is a monolithic switching regulator designed for isolated flyback converter applications. It integrates a high-voltage NPN power transistor with a fixed-frequency current-mode controller. The device supports an input voltage range from 10V to 60V and delivers up to 2.5A of output current. Operating at a fixed 500kHz switching frequency, it utilizes a TSSOP-EP-16 package to facilitate thermal dissipation. The integrated architecture simplifies design by combining the power switch and control logic into a single component.

Feature Summary

Integrates a 60V NPN power transistor with a current-mode controller
Supports isolated flyback topology for galvanic isolation
Fixed 500kHz switching frequency enables compact magnetic component selection

Applications

Isolated DC-DC conversion in industrial equipment
Power supplies for communication infrastructure
Battery-powered systems requiring isolation

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the procurement channel provides valid traceability for the #PBF lead-free designation. Confirm RoHS compliance status through the manufacturer's material declaration before integration into regulated assemblies.

Selection Notes

Select this component when an integrated solution for isolated flyback topologies is required. The internal 60V rating accommodates standard input ranges without external clamping. Evaluate thermal performance requirements based on the TSSOP-EP-16 package capabilities and expected load conditions.

Part Context

This part belongs to the LT3575 family of monolithic switching regulators. It is distinct from non-isolated buck converters like the LT3435 or multi-output regulators like the LT3514. The device specifically targets applications necessitating transformer-based isolation within a compact surface-mount footprint.
