Overview
The LT3957EUHE#PBF is a wide input range, current mode DC/DC converter manufactured by Analog Devices Inc. It supports Boost, Flyback, SEPIC, and Inverting topologies to generate positive or negative output voltages. The device operates with an input voltage range of 3 V to 40 V and delivers up to 5 A output current. Key electrical parameters include a 1 MHz switching frequency, 1 uA quiescent current, and operation within a temperature range of -40°C to +125°C. It utilizes a 36-lead QFN package.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting configurations for flexible voltage generation.
- Capable of generating either positive or negative output voltages from a single input source.
- Features low quiescent current consumption suitable for battery-powered applications.
Applications
- Industrial control systems requiring isolated or inverted power rails
- Battery-powered equipment needing efficient step-up or step-down conversion
- Automotive electronics operating within wide input voltage ranges
Procurement Notes
Verify the specific suffix and package type against official datasheets before ordering. Confirm availability status as supply may be limited. Ensure compatibility with required thermal management solutions for the QFN-36 package. Check RoHS compliance documentation if required for your region.
Selection Notes
Select this component when application requires flexibility in topology selection such as SEPIC or inverting converters. Consider the 40V maximum input rating and 5A current capability against load requirements. Evaluate thermal performance needs given the 36-lead QFN package constraints.
Part Context
This part belongs to the LT3957 series of high-performance DC/DC converters designed for demanding industrial and automotive environments. It integrates current mode control architecture to provide stable regulation across varying input and load conditions.
Replacement Considerations
LT3959EUHE#PBF offers similar functionality with different current ratings and pinout characteristics. Verify pin compatibility and electrical specifications before substitution.
