Overview
The LT3757EMSE#TRPBF is a DC/DC switching controller from Analog Devices, designed for wide input range applications. It supports Boost, Flyback, SEPIC, and Inverting topologies with positive or negative outputs. The device operates within a supply voltage of 2.9V to 40V and features a switch frequency range of 100kHz to 1MHz. Packaged in a 10-MSOP-EP surface-mount format, it includes clock synchronization, soft start, and enable functions. Operating temperatures span from -40°C to +125°C.
Feature Summary
- Supports multiple converter topologies including Boost, Flyback, SEPIC, and Inverting configurations.
- Capable of generating both positive and negative output voltages.
- Features clock synchronization for multi-phase or parallel operation.
- Includes integrated soft start and enable control functions.
Applications
- Industrial power supplies requiring flexible topology options
- Automotive electronics utilizing wide input voltage ranges
- Telecommunications equipment needing isolated or non-isolated conversion
- Battery-powered systems requiring step-up or step-down capabilities
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the 10-MSOP-EP package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent product change notices regarding epoxy or marking changes. Validate that the supplier provides official Analog Devices documentation for quality assurance.
Selection Notes
Choose this controller when application requires flexibility across multiple topologies like Boost, Flyback, or SEPIC. Select for designs needing synchronized switching frequencies to reduce EMI or allow phase interleaving. Consider for systems requiring both positive and negative outputs from a single controller. Ideal for wide input voltage ranges where current mode control offers stability. Evaluate thermal performance given the MSOP-EP package's exposed pad requirement for heat dissipation.
Part Context
The LT3757 series belongs to Analog Devices' portfolio of wide-input-range DC/DC controllers. It complements other parts like the LT3756 and LT3758 by offering versatile topology support. The EMSE variant specifically denotes the MSOP-EP package suitable for surface mount assembly. This component serves as a core switching element in various power conversion architectures.
Replacement Considerations
LT3757EMSE#PBF is the tube-pack equivalent of the same functional device. LT3757AEMSE#TRPBF offers similar functionality with potential minor electrical specification variations; consult datasheet for details. No direct cross-brand substitutes are confirmed without further verification.
