DC DC Switching Controllers datasheet and documents for LTC3780MPG#PBF
DC DC Switching Controllers Overview
The LTC3780MPG#PBF is a high-efficiency, synchronous four-switch buck-boost DC/DC controller designed for applications requiring operation with input voltages above, equal to, or below the output voltage. It operates within an input voltage range of 4V to 36V and provides an adjustable output voltage from 0.8V to 30V. The device supports up to 20A of output current and features a switch frequency of 440kHz. It is housed in a 24-pin SSOP package and is qualified for military-grade operation across a temperature range of -55°C to +125°C.
DC DC Switching Controllers Feature Summary
- Synchronous four-switch topology enables efficient buck-boost conversion without transformers
- Military-grade reliability with extended temperature qualification
- Integrated control logic for external MOSFET drive
DC DC Switching Controllers Applications
- Automotive power systems with wide input variations
- Industrial battery-powered equipment
- Telecommunications backup power supplies
DC DC Switching Controllers Procurement Notes
Verify the specific suffix 'MPG' confirms military grade qualification and SSOP packaging when sourcing. Confirm RoHS compliance status as required by project specifications. Ensure the manufacturer is Analog Devices Inc. Cross-reference the full part number against official distributor catalogs to validate authenticity and avoid counterfeit components.
DC DC Switching Controllers Selection Notes
Select this component for designs requiring robust performance under extreme environmental conditions. The military rating ensures stability where commercial parts may fail. Verify that the 24-pin SSOP footprint fits the PCB layout constraints. Ensure the external component selection supports the 440kHz switching frequency and 20A current capability.
DC DC Switching Controllers Part Context
This controller belongs to the LTC3780 family of high-performance buck-boost regulators. While other variants like the IUH or EUH offer industrial ratings, the MPG variant specifically targets defense and aerospace sectors. It shares core functionality with the standard LTC3780 but meets stricter manufacturing and testing standards for harsh environments.
DC DC Switching Controllers Replacement Considerations
LTC3780EUH#PBF offers similar electrical performance but lacks military temperature qualification. LTC3780IUH#PBF provides industrial grade reliability. Direct substitution requires verifying package compatibility and thermal management requirements.
