MAX1748EUE+

Overview

The MAX1748EUE+ is a triple-output TFT LCD voltage regulator IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an input voltage range of 2.7 V to 5.5 V and features a switching frequency of 1 MHz. The device delivers three independent regulated outputs, with typical quiescent current consumption of 600 uA. It is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides three independent output voltage rails for flexible power distribution
• Optimized for driving TFT LCD panels with integrated charge pump technology
• Operates at a high switching frequency to minimize external component size

Applications

• TFT LCD panel power supply systems
• Portable electronic devices requiring multiple voltage rails
• Mobile communication equipment display drivers

Procurement Notes

Verify the specific suffix 'EUE+' against the official datasheet to confirm the lead-free status and tape-and-reel or tube packaging configuration. Ensure the supplier provides traceability documentation consistent with Analog Devices specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when designing power supplies for TFT LCD applications requiring three distinct voltage levels from a single low-voltage source. Consider the 600 uA quiescent current for battery-operated systems where efficiency is critical. Verify that the required output voltages fall within the adjustable ranges supported by the internal feedback network and that the thermal performance of the TSSOP-16 package meets the system's dissipation requirements.

Part Context
