XC9516A21AZR-G

Overview

The XC9516A21AZR-G is an LCD driver and triple output power supply designed for TFT-LCD applications. Manufactured by Torex Semiconductor, it operates within a supply voltage range of 2.5 V to 5.5 V. The device features a maximum clock frequency of 1.2 MHz and a maximum power dissipation of 300 mW. It consumes a maximum supply current of 4 uA. The component is housed in a QFN-20 package and supports surface mount installation. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates LCD driving capabilities with triple output power supply functions specifically for TFT-LCD panels
• Operates with low supply current consumption suitable for portable electronic devices
• Supports surface mount technology in a compact QFN-20 package

Applications

• TFT-LCD panel driving systems
• Portable electronic display modules
• Consumer electronics requiring integrated LCD power and drive solutions

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with Torex Semiconductor or authorized distributors before procurement. Confirm that the QFN-20 package dimensions align with your PCB footprint requirements. Ensure that the input voltage range of 2.5 V to 5.5 V matches your system's power rail specifications. Check for any recent lifecycle updates or end-of-life notifications from the manufacturer to ensure long-term availability for production.

Selection Notes

Select this component when a single IC solution is required to handle both LCD signal driving and multiple power rails for TFT-LCD applications. Consider the 1.2 MHz clock frequency limit and 300 mW power dissipation capability against your thermal design constraints. The QFN-20 package size should be evaluated against available board space. Verify that the 4 uA supply current meets your system's power efficiency targets compared to alternative drivers.

Part Context

This part belongs to the XC9516 series of LCD drivers produced by Torex Semiconductor. It is categorized under Driver ICs within the broader PMIC and display driver market segment. The device represents a specialized integration of display control and power management functions, distinct from general-purpose switching regulators like the XC9519 series. It targets applications requiring dedicated TFT-LCD support rather than generic voltage regulation.

Replacement Considerations

No public confirmed substitute part numbers are identified in the provided documentation. Cross-reference with other Torex LCD driver models in the XC9516 series for potential pin-compatible alternatives if available. Consult official distributor databases for direct replacements based on updated component lifecycles.
