ACT88420-101T

Overview

The Qorvo ACT88420-101T is a highly configurable, programmable constant on-time (COT) power management integrated circuit designed for space-constrained applications. It features six voltage rails, including two 4 A and two 2 A buck regulators, plus two 400 mA LDOs. The device supports an input voltage range of 2.7 V to 5.5 V and operates within a temperature range of -40°C to +105°C. Regulators 1 and the first LDO are configurable as load switches, while regulator 4 functions as a dedicated 400 mA LDO. It utilizes a compact 36-ball WLCSP package measuring 2.66 x 2.66 mm.

Feature Summary

• Highly configurable architecture allowing I2C reprogramming without PCB changes
• Integrated programmable power sequencing and eight configurable tri-state GPIOs
• Compact footprint with minimal external component requirements
• Supports multiple SKU operations through flexible pinout and functional mapping

Applications

• Internet of Things (IoT) devices
• Point-of-sale (POS) terminals
• Network cameras
• Space-constrained industrial designs

Procurement Notes

Verify the specific suffix '101T' against official Qorvo documentation to confirm tape-and-reel packaging specifications and exact electrical tolerances. Ensure compatibility with ActiveCiPS programming tools for configuration. Cross-reference the latest datasheet revision to confirm thermal performance ratings and package dimensions prior to final procurement decisions.

Selection Notes

Select this PMIC when design constraints require high integration in a small area. It is suitable for systems needing multiple regulated outputs from a single wide-input source. Consider its programmability if future product variants require different power profiles without hardware redesign. Evaluate the need for load switch functionality on specific rails before finalizing the selection.

Part Context

The ACT88420 belongs to Qorvo's Advanced COT PMIC family, which emphasizes flexibility and miniaturization. This series targets modern embedded systems where board real estate is limited. The part integrates control logic with power stages to reduce bill of materials complexity. It represents Qorvo's strategy to provide software-defined power solutions for diverse electronic markets.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate other members of the ACT884xx series for pin-compatible alternatives or assess broader Qorvo PMIC portfolios for functional equivalents if supply constraints arise.
