RT5028AGQW

Overview

The RT5028AGQW is a highly integrated analog System on Chip (SoC) and Power Management IC (PMIC) designed for industrial applications. It features four synchronous step-down DC-DC converters and eight Low Dropout (LDO) regulators within a single 56-WQFN package. The device operates with a supply voltage range of 2.5 V to 5.5 V and supports switching frequencies between 500 kHz and 2 MHz. Output voltages are adjustable, ranging from 0.7 V to 3.6 V depending on the specific regulator channel, with current capabilities up to 2.4 A. It includes embedded MTP non-volatile memory for configuration.

Feature Summary

• Integrates four synchronous buck converters and eight LDOs in a single chip
• Includes embedded MTP non-volatile memory for system sequence and timing configuration
• Designed specifically for industrial application environments
• Provides comprehensive power management solutions with IRQ reporting

Applications

• Industrial control systems
• Automotive electronics
• Multi-rail power distribution networks
• Complex embedded systems requiring high integration

Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to ensure correct pinout and feature set. Confirm RoHS compliance status and lead times directly with authorized distributors or Richtek USA Inc. prior to ordering. Ensure ESD protection measures are followed during handling due to the sensitive nature of the integrated circuit components.

Selection Notes

Select this component when a high degree of integration is required to reduce board space and simplify power architecture. It is suitable for designs needing multiple regulated outputs from a single input source. Consider the thermal performance of the 56-WQFN package and the need for external passive components associated with the synchronous buck converters.

Part Context

This part belongs to Richtek's portfolio of advanced PMICs aimed at reducing complexity in industrial and automotive designs. It consolidates multiple discrete voltage regulation functions into one SoC, offering advantages in size reduction and design flexibility compared to using separate regulator ICs.
