LT3757AEDD#PBF

Overview

The LT3757AEDD#PBF is a wide input range, current mode DC/DC controller from Analog Devices. It supports Boost, Flyback, SEPIC, and Inverting topologies to generate positive or negative output voltages. The device operates with a supply voltage of 2.9V to 40V and features an adjustable switching frequency from 100 kHz to 1 MHz. It includes clock synchronization, soft start, and enable functions. Packaged in a 10-lead DFN (3x3mm) with exposed pad, it operates within a temperature range of -40°C to +125°C.

Feature Summary

Supports multiple converter topologies including Boost, Flyback, SEPIC, and Inverting configurations for versatile power design applications.
Features clock synchronization capability to allow phase alignment and noise reduction in multi-controller systems.
Integrates control characteristics such as soft start and shutdown functionality for reliable system startup and management.

Applications

Industrial power supplies requiring isolated or non-isolated conversion
Automotive electronics operating under wide input voltage conditions
Telecommunications equipment utilizing SEPIC or inverting architectures

Procurement Notes

Verify the specific suffix PBF indicates lead-free compliance and RoHS standards before procurement. Confirm the package type matches the 10-WFDFN specification with exposed thermal pad requirements. Ensure the ordering quantity aligns with tube packaging constraints rather than tape and reel formats. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability status.

Selection Notes

Select this component when designing circuits requiring a single controller for multiple topology options. Consider the 2.9V to 40V input range suitability for various bus voltages. Evaluate the need for clock synchronization if electromagnetic interference mitigation is required. Verify that the 10-DFN package fits the available PCB real estate and thermal dissipation capabilities.

Part Context

This part belongs to the LT3757 family of DC/DC controllers designed for high-performance power management. It serves as a core control element for generating regulated outputs in complex power stages. The LT3757A variant offers specific electrical characteristics optimized for industrial and automotive environments compared to standard versions.
