EL7583IREZ-T7

Special Purpose Regulators Overview

The EL7583IREZ-T7 is a switching voltage regulator manufactured by Intersil, now part of Renesas Electronics. It functions as a 3-channel DC/DC converter designed for power management applications. The device utilizes pulse width modulation (PWM) control technology to regulate output voltages efficiently. It operates within an input voltage range from 2.7 V to 14 V, with a nominal input voltage of 3.3 V. The maximum switching frequency is specified at 1000 kHz. The component is housed in a 20-pin HTSSOP package, measuring 6.5 mm in length. It is rated for operation in temperatures ranging from -40°C to 85°C and complies with RoHS standards.

Special Purpose Regulators Feature Summary

• Integrates three independent DC/DC converter channels within a single compact package
• Employs pulse width modulation (PWM) control technique for efficient voltage regulation
• Operates over a wide input voltage range supporting nominal 3.3 V systems
• Designed for surface mount installation in industrial temperature environments

Special Purpose Regulators Applications

• Power supply circuits for LCD panel drivers
• TFT LCD bias voltage generation
• General purpose DC/DC conversion in portable electronics
• Multi-rail power distribution systems

Special Purpose Regulators Procurement Notes

Verify the manufacturer designation carefully, as the component is listed under both Intersil and Renesas Electronics due to corporate acquisition history. Confirm the specific suffix 'T7' corresponds to the required tape and reel packaging configuration for automated assembly processes. Ensure the HTSSOP-20 package variant matches the footprint requirements of the target design. Check current availability status as some variants in this series may be discontinued or subject to last-time buy notices.

Special Purpose Regulators Selection Notes

Select this component when a multi-output power solution is required for display driver applications. The 3-channel architecture reduces board space compared to discrete regulators. Consider the 1000 kHz switching frequency for balancing efficiency and passive component size. Verify that the 14 V maximum input voltage aligns with the system's power source. The -40°C to 85°C operating range suits standard commercial and industrial environments. Ensure the PWM control interface is compatible with the system's feedback network requirements.

Special Purpose Regulators Part Context

The EL7583 belongs to the EL7583 series of switching regulators specifically engineered for LCD and TFT display applications. This family provides integrated solutions for generating multiple voltage rails needed by display panels. The IREZ-T7 designation indicates the specific package type, lead finish, and packaging method. Related parts in the series include variants with different output counts or package styles, such as the EL7583IRZ. The series represents a transition period between Intersil branding and Renesas Electronics product lines.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official distributor databases for cross-reference information. Direct pin-to-pin replacements may require verification of electrical parameter compatibility. Alternative solutions might involve discrete regulator designs if integrated options are unavailable.
