MAX17116EVC+T

Overview

The MAX17116EVC+T is a dual-output DC-DC converter designed for active-matrix organic light-emitting diode (AMOLED) displays. It integrates two current-mode switch mode power-supply regulators operating at a fixed frequency of 1.4MHz. The device accepts an input voltage range of 2.3V to 4.2V and provides two regulated outputs: a positive output of 4.6V and a negative output of -4.9V. Packaged in a 12-UTDFN-EP (3x3) surface-mount enclosure, this integrated circuit serves as a compact power management solution for display applications requiring precise voltage regulation.

Feature Summary

• Integrates two independent current-mode switching regulators optimized for AMOLED display biasing requirements
• Operates with a fixed high-frequency switching architecture to minimize external component size
• Provides dedicated positive and negative voltage rails suitable for display panel driving

Applications

• Active-matrix organic light-emitting diode (AMOLED) display power systems
• Mobile device display bias circuits
• Compact portable electronics requiring dual-rail power conversion

Procurement Notes

Verify the obsolete status of this specific part number before initiating any procurement activities. Confirm that the 12-UTDFN-EP package dimensions match your board layout constraints. Ensure compatibility with the specified 2.3V to 4.2V input range for your target application. Cross-reference the manufacturer's latest documentation to confirm pinout integrity against potential legacy revisions.

Selection Notes

Select this component when designing power supplies for AMOLED displays requiring simultaneous positive and negative rail generation. The dual-regulator topology reduces board space compared to discrete solutions. Consider the 1.4MHz switching frequency for trade-offs between efficiency and passive component sizing. Verify that the input voltage range aligns with the system battery or supply characteristics.

Part Context

This device belongs to the Maxim Integrated power management portfolio, specifically engineered for display driver applications. It consolidates dual regulator functions into a single small-footprint package. The technology supports modern mobile and wearable devices where space efficiency is critical. It represents a specialized solution for driving OLED panels rather than general-purpose power conversion.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Due to the obsolete status, direct replacements may require evaluating newer generations from Analog Devices or functional equivalents from other manufacturers with compatible dual-output specifications.
