Overview
The LT3757MPMSE#PBF is a monolithic DC/DC switching controller manufactured by Analog Devices Inc., designed for high-performance power conversion applications. It supports multiple topologies including Boost, Flyback, SEPIC, and Inverting configurations. The device features a wide input voltage range from 2.9V to 40V and an adjustable switching frequency between 100 kHz and 1 MHz. It provides a single output with a drive capability of 20 mA at 7.2 V. The component operates within a temperature range of -55°C to +150°C and is housed in a 10-MSOP-EP package.
Feature Summary
- Supports versatile converter topologies including boost, flyback, SEPIC, and inverting configurations for positive and negative outputs
- Features clock synchronization capability to allow external timing control
- Includes integrated soft-start functionality to manage inrush current during startup
- Offers enable and frequency control features for flexible system management
Applications
- Telecom power supplies
- Portable electronic equipment
- Industrial power systems requiring isolated or non-isolated DC/DC conversion
Procurement Notes
Verify the specific suffix and tape/reel specifications against the official Analog Devices datasheet prior to ordering. Confirm that the 10-MSOP-EP package dimensions match your PCB footprint requirements. Ensure that the extended military-grade temperature rating aligns with your thermal design constraints. Cross-reference the part number with the manufacturer's latest availability status to avoid supply chain disruptions.
Selection Notes
Select this component when designing circuits requiring a wide input voltage range up to 40V and support for multiple converter topologies. It is suitable for applications needing synchronized switching frequencies to reduce EMI interference. Consider the 20 mA output drive strength for gate driving external MOSFETs. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
The LT3757 belongs to Analog Devices' family of advanced DC/DC controllers. It is often paired with development boards such as the DC1341A for evaluation purposes. The MP variant denotes military-grade performance with extended temperature capabilities compared to standard commercial versions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices for direct replacements or cross-references.
