Overview
The LT3757MPMSE#TRPBF is a high-performance DC-DC switching controller manufactured by Analog Devices Inc., designed for versatile power conversion topologies including boost, flyback, SEPIC, and inverting configurations. It supports both positive and negative output voltages with step-up and step-down capabilities. The device operates within a supply voltage range of 2.9V to 40V and features an adjustable switching frequency from 100kHz to 1MHz. It utilizes current mode control architecture and includes clock synchronization functionality. The component is housed in a 10-MSOP-EP package with exposed pad for thermal management.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting circuits
- Enables generation of both positive and negative output voltages from a single input source
- Features programmable switching frequency with external clock synchronization capability
- Integrates soft-start and enable functions for controlled power sequencing
Applications
- Industrial power supplies requiring isolated or non-isolated regulation
- Battery-powered systems utilizing SEPIC topology for wide input voltage ranges
- Communication equipment needing negative rail generation from positive sources
- Automotive electronics requiring robust step-up/step-down conversion
Procurement Notes
Verify the exact suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the MP grade meets military temperature specifications if required for your application. Ensure compatibility with 10-MSOP-EP footprint during PCB layout. Check latest datasheet revisions for any changes in electrical characteristics or recommended operating conditions before finalizing design.
Selection Notes
Choose this controller when flexible topology support is needed alongside precise current-mode regulation. Consider the 10-MSOP-EP package for space-constrained designs requiring efficient heat dissipation. Evaluate the 100kHz to 1MHz frequency range against EMI requirements and passive component sizing needs. Verify that the 2.9V to 40V input range aligns with system power availability.
Part Context
The LT3757 series belongs to Analog Devices' portfolio of advanced switching controllers designed for complex power architectures. It complements other devices like the LT3758 which offers higher input voltage capabilities. The MP variant denotes military-grade performance with extended temperature ranges compared to commercial versions. This component fits within the broader category of PMIC solutions for industrial and aerospace applications.
Replacement Considerations
LT3757IMSE#PBF serves as a commercial-grade alternative with identical pinout and functionality but different temperature ratings. LT3757AEMSE#TRPBF offers enhanced performance specifications while maintaining compatibility. Verify package dimensions and thermal pad connectivity when substituting. Review datasheet differences regarding switching frequency limits and drive strength.
