DA9214-XXUP6

Overview

The DA9214-XXUP6 is a dual-channel, two-phase multiphase DC/DC buck converter sub-PMIC designed for high-current applications. It integrates power switches to deliver up to 10A per channel, supporting scalable configurations for demanding loads. The device features a wide input voltage range and adjustable output voltages with high accuracy. It incorporates dynamic voltage control (DVC) and remote sensing capabilities to optimize efficiency and transient response. The component is housed in a compact VFBGA package suitable for space-constrained designs.

Feature Summary

• Dual-channel architecture providing independent or parallel output configurations
• Integrated power switches eliminating the need for external FETs
• Dynamic Voltage Control (DVC) for adaptive supply voltage adjustment
• Remote sensing capability at the point of load for improved regulation

Applications

• Multi-core System on Chips (SoCs)
• Graphics Processing Units (GPUs)
• Field Programmable Gate Arrays (FPGAs)

Procurement Notes

Verify current availability status as supply may be limited or subject to factory special orders. Confirm that the specific suffix matches the required pinout and configuration. Ensure compatibility with existing board layouts and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual isolated rails or high-current parallel operation are required for complex digital loads. Evaluate the need for DVC functionality to meet specific processor power profiles. Consider the VFBGA package constraints and ensure adequate PCB real estate for the required inductor placement and thermal dissipation paths.

Part Context

This part belongs to the DA921x series of multiphase buck converters from Renesas. It serves as a sub-PMIC solution, typically paired with a main PMIC to handle high-power digital cores. The series is engineered for low output ripple and high efficiency across wide load ranges, targeting portable and embedded computing platforms.

Replacement Considerations

Public confirmed substitutes include the DA9213-A and DA9210-A. Verify pin-to-pin compatibility and electrical parameter alignment, particularly regarding maximum output current and switching frequency, before implementing any alternative components.
