EL7520ILZ-T13

Special Purpose Regulators Overview

The EL7520ILZ-T13 is a DC/DC controller designed for TFT LCD applications, manufactured by Renesas Electronics Corporation. It features four independent output channels and operates within an input voltage range of 3V to 5.5V. The device utilizes current-mode control with pulse width modulation technology. It is housed in a 20-QFN (4x4) package with exposed pad and supports surface mount installation. The component functions across a temperature range of -40°C to 85°C and holds MSL level 3 classification.

Special Purpose Regulators Feature Summary

• Four-channel DC/DC controller architecture optimized for TFT LCD power supplies
• Current-mode control technique utilizing pulse width modulation
• Integrated design supporting wide operating temperature ranges

Special Purpose Regulators Applications

• TFT LCD panel power management systems
• Multi-rail DC/DC conversion circuits
• Portable electronic display devices

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'T13' against official Renesas documentation to confirm reel quantity and tape specifications. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for any recent product change notices regarding packaging or labeling updates that may affect inventory handling procedures.

Special Purpose Regulators Selection Notes

Select this component when a multi-output solution is required for driving TFT LCD panels from a single low-voltage source. The integrated controller approach reduces external component count compared to discrete regulator designs. Ensure the application requires current-mode control characteristics and fits within the specified 3V to 5.5V input window.

Special Purpose Regulators Part Context

This part belongs to the EL7520 family of power management ICs. It serves as a specialized controller rather than a standalone regulator, requiring external switches. Related variants include the EL7520AILZ and EL7520ILZ-T7, which share similar core functionalities but differ in packaging or reel quantities.
