Overview
The LT3757EMSE#PBF is a switching controller from Analog Devices Inc. designed for Boost, Flyback, SEPIC, and Inverting topologies. It operates with a supply voltage range of 2.9V to 40V and supports a switching frequency between 100kHz and 1MHz. The device features clock synchronization capability and includes control characteristics such as enable, frequency control, and soft start. It is housed in a 10-MSOP-EP package with an exposed pad, suitable for surface mount installation. The component supports positive and negative outputs and functions within a junction temperature range of -40°C to 125°C.
Feature Summary
- Supports multiple converter topologies including Boost, Flyback, SEPIC, and Inverting configurations.
- Features clock synchronization for system timing alignment.
- Includes integrated control features such as enable pin, frequency control, and soft start functionality.
Applications
- Boost regulator designs
- Flyback converter implementations
- SEPIC power supply circuits
- Inverting voltage regulation systems
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm that the MSOP package variant matches the required board layout constraints. Ensure the supplier source provides valid traceability documentation for the Analog Devices Inc. manufacturer part number. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component when a versatile controller supporting multiple non-isolated and isolated topologies is required. The wide input voltage range accommodates various supply sources. Consider the 10-MSOP-EP package for thermal management needs due to the exposed pad. Verify that the external MOSFET selection aligns with the controller's drive capabilities and the target switching frequency range.
Part Context
The LT3757EMSE#PBF belongs to the LT3757 series of DC/DC switching controllers. This series is designed to offer flexibility in power architecture by supporting various standard converter topologies within a single IC family. The EMSE designation specifies the MSOP package type, distinguishing it from other package variants like DFN or IDD available in the same product line.
Replacement Considerations
LT3757AIDD#PBF offers similar functionality in a DFN package. LT3757AIMSE#TRPBF provides the same electrical performance in a tape and reel format. LT3757EMSE#TRPBF is the reel version of the same package. Verify pinout and thermal pad requirements when substituting between package types.
