DC DC Switching Controllers datasheet and documents for LTC3868EGN-1#PBF
DC DC Switching Controllers Overview
The LTC3868EGN-1#PBF is a dual-phase synchronous step-down switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4 V to 24 V and supports output voltages from 800 mV to 14 V. The device delivers up to 25 A of output current per phase with a switch frequency adjustable between 75 kHz and 850 kHz. Quiescent current is specified at 170 uA, and load regulation is rated at 0.01%. It is housed in a 28-SSOP package and functions within a temperature range of -40°C to +85°C.
DC DC Switching Controllers Feature Summary
- Dual-channel architecture providing independent control for two synchronous buck phases
- Low quiescent current consumption for improved efficiency during light-load conditions
- Adjustable switching frequency allows optimization for specific design requirements
DC DC Switching Controllers Applications
- Industrial distributed power systems
- Telecommunications infrastructure equipment
- Point-of-load voltage regulation modules
DC DC Switching Controllers Procurement Notes
Verify component authenticity through authorized channels due to limited supply status. Confirm RoHS compliance documentation matches the specific manufacturing lot. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet prior to assembly. Cross-reference ordering suffixes to confirm package type and tape/reel specifications.
DC DC Switching Controllers Selection Notes
Select this controller when dual high-current outputs are required from a single IC footprint. Evaluate thermal management capabilities based on the 28-SSOP package constraints. Compare against alternative models if higher input voltage ranges or different pin configurations are necessary for the target application layout.
DC DC Switching Controllers Part Context
This component belongs to the LTC3868 family of low IQ dual synchronous step-down controllers. It shares functional similarities with other members like the LTC3868IGN-1#PBF but differs in operating temperature range and packaging style. The EG suffix indicates commercial grade operation compared to industrial variants.
DC DC Switching Controllers Replacement Considerations
LTC3868IGN-1#PBF serves as a direct functional substitute with identical electrical characteristics but offers an extended industrial temperature range.
