Overview
The LT3845EN#PBF is a high voltage, synchronous, current mode buck controller from Analog Devices. It supports input voltages from 4V to 60V and delivers up to 15A output current. The device features an adjustable switching frequency range of 100kHz to 500kHz, with a typical operating point at 300kHz. Quiescent current is specified at 120µA. It operates within a temperature range of -40°C to +125°C and utilizes a 16-pin DIP package.
Feature Summary
- Synchronous current mode control architecture for high efficiency
- Wide 4V to 60V input voltage capability
- Integrated soft start and enable functions
- Adjustable switching frequency for EMI optimization
Applications
- High power density industrial power supplies
- Distributed power systems
- Telecommunications infrastructure
- Automotive electronics
Procurement Notes
Verify the specific suffix EN#PBF corresponds to the 16-pin DIP through-hole package variant. Confirm RoHS compliance status via official documentation. Check lead times as availability may be restricted. Ensure ordering matches the exact Analog Devices part number to avoid pinout or electrical mismatches.
Selection Notes
Select this component for applications requiring wide input voltage ranges up to 60V. The synchronous design reduces external component count compared to non-synchronous alternatives. Consider thermal management requirements for the 15A output capability. Verify that the 16-pin DIP package fits the target PCB layout constraints.
Part Context
This part belongs to the LT3845 family of high voltage synchronous buck controllers. It shares architectural similarities with other members like the LT3845EFE#PBF but differs in packaging. The EN#PBF designation specifically indicates the through-hole DIP configuration suitable for prototyping or specific mounting needs.
Replacement Considerations
