Overview
The ADP1882ARMZ-0.3-R7 is a synchronous current-mode buck switching controller manufactured by Analog Devices Inc. It operates at a maximum switching frequency of 300kHz and utilizes a constant on-time architecture. The device features a 0.8V reference voltage and supports positive output configurations with transistor drivers. It is housed in a 10-MSOP package, rated for operation between -40°C and +125°C TJ, and accepts supply voltages from 3V to 20V.
Feature Summary
- Synchronous current-mode control topology for high efficiency
- Constant on-time architecture for stable operation
- Integrated enable control feature
Applications
- Step-down DC/DC power conversion systems
- Efficient power management modules
- Industrial equipment power supplies
Procurement Notes
Verify the specific suffix '0.3' against official Analog Devices documentation to confirm internal parameter variations or revision levels. Ensure the 10-MSOP package type matches the target PCB footprint requirements. Confirm that the 300kHz switching frequency aligns with system noise and efficiency constraints before finalizing procurement orders.
Selection Notes
Select this component when a synchronous buck controller with constant on-time behavior is required. The 0.8V reference voltage dictates the feedback resistor network design. Verify that the input voltage range of 3V to 20V covers the application's supply rails. Ensure thermal management supports the specified junction temperature range during continuous operation.
Part Context
This part belongs to the ADP1882 family of DC/DC switching controllers. It is designed for applications requiring efficient step-down conversion with simplified external component counts. The device integrates necessary driver stages for synchronous rectification, reducing the need for external gate drive circuitry compared to non-synchronous alternatives.
Replacement Considerations
Cross-reference with ADP1882 variants having different suffixes for potential pin-compatible upgrades. Verify electrical compatibility regarding reference voltage and switching frequency before substituting.
