Overview
The EL7531IYZ-T7 is a synchronous, integrated FET step-down regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.5 V to 5.5 V and provides an adjustable output voltage from 0.8 V to 5.5 V. The device delivers a maximum output current of 1 A. It features an internal switching frequency of 1.4 MHz and includes synchronous rectification for improved efficiency. The component is housed in a 10-MSOP package and supports surface mount installation. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Synchronous integrated FET step-down topology
- Internal compensation circuitry
- Adjustable output voltage capability
Applications
- Personal Digital Assistants (PDAs)
- Pocket PCs
- Bar code readers
- Cellular phones
Procurement Notes
Verify the specific suffix T7 indicates tape and reel packaging when sourcing. Confirm the manufacturer as Renesas Electronics Corporation or Intersil legacy branding. Check datasheet revisions for any pinout or electrical parameter updates. Ensure the 10-MSOP package dimensions match your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component for applications requiring a compact 1 A buck converter with low external component count due to internal compensation. The 1.4 MHz switching frequency allows for smaller inductors compared to lower frequency alternatives. Ensure the input voltage source stays within the 2.5 V to 5.5 V operational window. Consider the 10-MSOP thermal performance for high ambient temperature environments.
Part Context
The EL7531 belongs to the EL753x series of monolithic step-down regulators from Renesas/Intersil. It shares architectural similarities with the EL7530 but offers higher current capacity. The IYZ suffix denotes the industrial temperature grade and MSOP package variant. This series targets portable electronics where space and efficiency are critical constraints.
Replacement Considerations
EL7530IYZ-T7: Lower current rating (600 mA) but similar package and functionality. Verify if the reduced current meets system requirements. No other direct public substitutes are confirmed in the provided data.
