Overview
The ADP3806JRUZ-R7 is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 18V and delivers up to 4A of output current. The device features adjustable switching frequencies from 500kHz to 2.2MHz, integrated power MOSFETs, and comprehensive protection mechanisms including overcurrent, thermal, and UVLO. Packaged in a 24-lead LFCSP-WQ (4x4mm) for efficient thermal performance.
Feature Summary
- Integrated high-side and low-side N-channel power MOSFETs for compact design
- Synchronous rectification architecture for enhanced efficiency
- Programmable soft-start and frequency synchronization capabilities
- Built-in thermal shutdown and cycle-by-cycle current limiting
Applications
- Industrial automation control systems
- Telecommunications infrastructure equipment
- Portable battery-powered instrumentation
Procurement Notes
Verify the specific suffix 'JRUZ' against official Analog Devices documentation to confirm package type and temperature grade. Confirm RoHS compliance status via the latest datasheet revision. Ensure compatibility with PCB footprint dimensions specified in the mechanical drawing prior to procurement.
Selection Notes
Select this component when a wide input voltage range and moderate output current are required. Evaluate thermal requirements based on ambient conditions and load profile. Compare switching frequency options against EMI constraints and external component size limitations. Verify that the available packages meet spatial constraints within the target application enclosure.
Part Context
This part belongs to the ADP380x family of synchronous buck converters designed for industrial and telecom applications. It offers a balance of performance and integration, featuring internal power switches to reduce external component count. The family supports various packaging options to suit different thermal and board space requirements.
Replacement Considerations
Check for direct pin-compatible alternatives within the ADP380x series or newer generations such as the ADP238x family. Verify that any substitute maintains the same input voltage range, output current capability, and package dimensions.
