MAX17113ETL+T

Overview

The MAX17113ETL+T is a specialized PMIC for LCD TVs, operating at 8V to 16.5V input. It integrates a current-mode step-up regulator with a built-in 24V, 3.3A, 80mΩ n-channel MOSFET and a step-down regulator with a 24V, 3A, 100mΩ n-channel MOSFET. Features include selectable frequencies of 450kHz or 600kHz, high-accuracy output voltage regulation of 1%, and true shutdown capability. The device supports adjustable positive and negative charge-pump regulators, logic-controlled high-voltage integrated switches, and a 120mΩ p-channel FET for AVDD sequencing. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates step-up, step-down, and charge-pump regulators in a single compact package
• Includes built-in power MOSFETs for efficient power conversion
• Provides logic-controlled high-voltage integrated switches with adjustable delay
• Features internal soft-start and timer-delay fault latch for all outputs

Applications

• Power supply for TFT liquid-crystal display (LCD) panels in TVs
• Supplying source drivers, gate drivers, and panel logic circuits
• Multiple-output power solutions for LCD monitors

Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm the specific suffix 'T' indicates reel packaging if required by assembly processes. Ensure compatibility with existing board designs given the 40-pin TQFN footprint. Cross-reference pinouts with official datasheets to avoid integration errors during replacement or legacy system maintenance.

Selection Notes

Select this component for applications requiring a highly integrated power solution for LCD TV panels. It is suitable where space constraints necessitate combining multiple regulator functions into one IC. Consider its efficiency and thermal performance for dense PCB layouts. Verify that the input voltage range matches the system's power supply rails and that the output requirements align with the integrated regulators' capabilities.

Part Context

The MAX17113 is part of Maxim Integrated's portfolio of specialized power management ICs designed for display applications. It utilizes proprietary high-voltage BiCMOS technology to integrate multiple power stages on a small die area. This approach reduces the overall solution size and cost compared to discrete component implementations, targeting the consumer electronics market for thin-film transistor LCD technologies.

Replacement Considerations

The product lifecycle status is listed as Obsolete. No direct public substitute part numbers are confirmed in the provided documentation. Engineers must evaluate alternative PMICs from Analog Devices or other manufacturers that offer similar integration levels for LCD TV applications, ensuring pin compatibility and electrical parameter alignment.
