MAX17031ETG+T

Overview

The MAX17031ETG+T is a Dual Quick-PWM, Step-Down Controller with Low-Power LDO and RTC Regulator for MAIN Supplies. It operates within an input voltage range of 6V to 24V and supports a supply current of 100µA. The device functions across an operating temperature range of -40°C to +85°C. It utilizes a 24-pin TQFN EP package (LFCSP-4X4X0.75) and employs current mode control for its dual-channel step-down regulation.

Feature Summary

• Dual Quick-PWM step-down controller architecture
• Integrated low-power LDO and RTC regulator
• Current mode control for fast transient response

Applications

• Main power supplies in portable electronics
• Battery-powered devices requiring efficient DC-DC conversion
• Systems needing integrated real-time clock support

Procurement Notes

Verify the exact suffix 'ETG+T' against the manufacturer's official ordering guide to ensure correct packaging and tape-and-reel specifications. Confirm that the 24-LFCSP package dimensions match your PCB footprint requirements. Check RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides valid traceability documentation for this active component.

Selection Notes

Select this component when a compact dual-step-down solution with integrated auxiliary regulators is required. It is suitable for applications demanding high efficiency and fast load-transient response within a small form factor. Consider the 6V to 24V input range compatibility with your system's power source. Evaluate the thermal performance of the exposed pad package for your specific enclosure constraints.

Part Context

This part belongs to Maxim Integrated's Quick-PWM family, designed for high-efficiency power management in space-constrained applications. It integrates multiple regulation functions into a single chip, reducing external component count. The device is manufactured by Analog Devices Inc., which acquired Maxim Integrated, ensuring continued support and availability for legacy designs.

Replacement Considerations

Check Analog Devices' official replacement matrix for direct pin-compatible or functionally equivalent alternatives. Verify that any substitute maintains the same 24-pin LFCSP package and electrical characteristics. Ensure the alternative supports the required 6V to 24V input range and dual-channel operation.
