Overview
The DA9217-20V72 is a single-channel dual-phase buck converter from the Renesas DA9217 series. It operates with an input voltage range of 2.5 V to 5.5 V and provides an adjustable output voltage between 0.3 V and 1.9 V. The device delivers up to 6 A of output current with a nominal switching frequency of 4 MHz. It features ±1% static accuracy and is housed in a compact WLCSP-24 package.
Feature Summary
- Single-channel dual-phase buck topology for efficient power conversion
- Compact WLCSP-24 packaging suitable for space-constrained designs
- High switching frequency enabling use of small external inductors
- Integrated shutdown capability for power management
Applications
- Supplying CPUs in smartphones and tablets
- Powering GPUs in handheld devices
- Providing DDR memory rails in mobile applications
- Powering RF modules in portable electronics
Procurement Notes
Verify the specific suffix '20V72' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with required input/output voltage ranges and thermal constraints for the target application environment before finalizing procurement.
Selection Notes
Select this component when a single high-current channel is required for CPU or GPU core voltage regulation in mobile devices. Consider the 4 MHz switching frequency for minimizing passive component size. Verify that the WLCSP-24 package fits within the PCB layout constraints and thermal design requirements of the system.
Part Context
The DA9217-20V72 belongs to the DA9217 SubPMIC family, designed for portable electronics. It integrates a dual-phase buck converter optimized for low noise and high efficiency. This part is specifically tailored for powering critical logic and memory components in smartphones, tablets, and other handheld devices requiring compact power solutions.
Replacement Considerations
Consult official Renesas substitution guides for verified alternatives. Generic replacements may not match the WLCSP-24 footprint or dual-phase control characteristics.
