Overview
The LT3800EFE#PBF is a high-voltage synchronous current mode step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 60V and supports a fixed switching frequency of 200kHz. The device features a 16-TSSOP-EP package with an exposed pad for thermal management. It provides one output configured as a transistor driver, suitable for positive or negative output applications. The controller includes enable functionality and operates within a junction temperature range of -40°C to 125°C.
Feature Summary
- Synchronous current mode control architecture for efficient power conversion
- High-voltage input capability up to 60V for flexible system design
- Integrated enable pin for precise power sequencing and shutdown control
Applications
- Industrial power supply systems requiring high input voltage tolerance
- Telecommunications infrastructure equipment
- Automotive electronics and battery-powered systems
- Point-of-load regulation in distributed power architectures
Procurement Notes
Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the 16-TSSOP-EP package dimensions match the PCB footprint requirements. Ensure the supplier provides valid documentation regarding the material declaration and REACH status for regulatory compliance checks before finalizing procurement orders.
Selection Notes
Select this component when a fixed 200kHz frequency is acceptable for the application's EMI constraints. The synchronous design requires external N-channel MOSFETs; ensure gate drive capabilities align with the controller's output specifications. Consider the thermal performance of the exposed pad solution if operating near maximum temperature limits or high load currents.
Part Context
This part belongs to the LT3800 series of high-voltage buck controllers from Analog Devices. It is designed for applications demanding robust performance across wide input voltage ranges. The device complements other Linear Technology power management solutions by offering a specialized topology for step-down conversion in harsh environments.
Replacement Considerations
LT3800EFE#TRPBF serves as a tape-and-reel alternative to the tube-packaged LT3800EFE#PBF, maintaining identical electrical characteristics and pinout compatibility for automated assembly processes.
