Overview
The LT7101MPUHE#PBF is a high-voltage synchronous step-down DC/DC converter manufactured by Analog Devices. It operates with an input voltage range of 4.5V to 105V and delivers up to 1A of continuous output current. The device utilizes the Silent Switcher architecture for low electromagnetic interference performance. It features a fixed switching frequency of 2MHz and supports adjustable output voltages from 0.8V to VIN. The component is housed in a thermally enhanced 36-lead QFN package and is rated for military-grade operation across a temperature range of -55°C to +150°C.
Feature Summary
- Silent Switcher architecture minimizes radiated EMI emissions without requiring external shielding or complex filtering components.
- Integrated power switches and control circuitry enable compact design within a single monolithic package.
- Wide input voltage capability allows direct connection to 48V automotive buses and industrial power systems.
Applications
- Automotive electronics requiring compliance with CISPR 25 Class 5 emission standards
- Industrial power distribution systems operating on 48V or higher bus architectures
- Telecommunications infrastructure power supplies
Procurement Notes
Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS directives. Confirm the MPUHE designation corresponds to the extended military temperature range specifications required for your application environment. Ensure compatibility with the 36-lead QFN footprint during PCB layout verification.
Selection Notes
Select this component when high input voltage tolerance and strict EMI limits are critical constraints. The fixed 2MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider thermal management requirements due to the high-power density inherent in the QFN-36 package form factor.
Part Context
This part belongs to the LT7101 family of high-voltage synchronous buck regulators. The MPUHE variant specifically denotes the military-grade temperature rating, distinguishing it from industrial (IUHE) or commercial (EUHE) equivalents which share identical electrical characteristics but differ in operational temperature limits.
Replacement Considerations
LT7101IUHE#PBF offers identical electrical performance with a reduced temperature range of -40°C to +125°C. LT7101EUHE#PBF provides the same functionality for standard industrial applications ranging from 0°C to +85°C.
