EL7642ILTZ-T13

Special Purpose Regulators Overview

The EL7642ILTZ-T13 is a switching voltage regulator from the Renesas EL7642 series, designed for TFT-LCD applications. It utilizes a boost topology to generate an output voltage of up to 18 V with a maximum output current of 150 mA. The device accepts an input voltage range between 2.6 V and 5.5 V and operates at a switching frequency of 1.2 MHz. It features three outputs and is housed in a 32-TQFN-EP package with dimensions of 5x5 mm. The component supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Integrated amplifier functionality specifically tailored for TFT-LCD DC-DC conversion requirements
• Boost topology configuration enabling efficient step-up voltage regulation from low input sources
• Multi-output capability providing three distinct regulated voltage rails from a single controller

Special Purpose Regulators Applications

• TFT-LCD power supply systems
• DC-DC conversion for display driver circuits
• Portable electronic devices requiring integrated power management

Special Purpose Regulators Procurement Notes

Verify the exact suffix designation carefully, as the requested model includes a T13 reel suffix while primary documentation often references ILTZ or T7 variants. Confirm availability status directly with authorized distributors, as this specific part number may be discontinued or subject to limited supply constraints. Ensure compliance with RoHS3 specifications and moisture sensitivity level 3 handling requirements during storage and assembly processes.

Special Purpose Regulators Selection Notes

Select this component when designing power stages for TFT-LCD panels requiring a compact solution with integrated amplification. Consider the 32-TQFN-EP package for thermal performance and space-constrained layouts. Evaluate the 1.2 MHz switching frequency against EMI constraints and inductor size requirements. Verify that the 150 mA output current meets the load demands of the target display application across the specified operating temperature range.

Special Purpose Regulators Part Context

The EL7642 belongs to the EL764x family of power management ICs developed by Renesas Electronics Corporation, formerly Intersil. This series targets portable electronics and display applications where high efficiency and small footprint are critical. The EL7642 specifically integrates a boost converter with an associated amplifier, distinguishing it from standard regulators in the broader PMIC portfolio.
