Overview
The ADPL42002ARDZ-1.8-R7 is a high-efficiency, synchronous step-down DC-to-DC converter from Analog Devices. It integrates a power stage capable of delivering up to 2A output current with an adjustable output voltage range. The device operates with an input voltage range typically spanning 3.5V to 24V. Key electrical characteristics include a switching frequency selectable between 600kHz and 2.2MHz. It features integrated soft-start, overcurrent protection, and thermal shutdown. The component is housed in a compact 4mm x 4mm QFN-28 package suitable for space-constrained designs.
Feature Summary
- Integrated synchronous buck converter architecture for high efficiency
- Wide input voltage range supporting various supply rails
- Programmable switching frequency for optimization of external components
- Built-in protection mechanisms including overcurrent and thermal limiting
Applications
- Industrial control systems requiring stable low-voltage power rails
- Telecommunications infrastructure equipment
- Portable battery-powered devices needing efficient power management
- Embedded computing modules and single-board computers
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the 1.8 designation matches the required fixed output voltage or adjustability if applicable. Check RoHS compliance status through official Analog Devices documentation prior to integration. Ensure ESD handling procedures are followed during assembly due to the sensitive nature of CMOS power ICs.
Selection Notes
Select this part when a compact solution for 2A loads is needed. Compare against the ADP5070 family for similar performance levels. Consider the thermal requirements of the QFN-28 package in your PCB layout. Verify that the desired switching frequency aligns with your inductor selection constraints. Review the datasheet for start-up time requirements relative to system sequencing needs.
Part Context
This component belongs to the ADPL42002 series of high-performance power management ICs. It is designed to replace older discrete solutions or less efficient linear regulators in modern electronics. The series emphasizes miniaturization and energy savings. It complements Analog Devices' portfolio of mixed-signal processing and power control products.
Replacement Considerations
Direct pin-compatible substitutes may include other ADI 2A buck converters like the ADP5070 variants. Cross-reference pinouts and thermal pads carefully. Verify electrical parameters such as quiescent current and ripple specifications match application requirements before substitution.
