Overview
The EL7562CUZ is a synchronous buck switching voltage regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 3.3 V to 5 V and provides a single adjustable output voltage between 1 V and 3.8 V. The device delivers a maximum output current of 2 A at a fixed switching frequency of 1 MHz. It features a load regulation of 0.5% and functions within an operating temperature range of 0°C to +70°C. The component is housed in a QSOP-16 surface-mount package.
Feature Summary
- Synchronous rectification topology for improved efficiency
- Fixed 1 MHz switching frequency for compact external component sizing
- Adjustable output voltage capability within specified limits
Applications
- Point-of-load DC-DC conversion for digital logic supplies
- Power management in portable electronic devices
- Embedded system voltage regulation
Procurement Notes
Verify the specific suffix 'CUZ' against the official Renesas datasheet to confirm package type and RoHS compliance status. Confirm end-of-life or obsolescence status through authorized distributors, as availability may be restricted. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent damage.
Selection Notes
Select this component when a 2 A synchronous buck converter is required from a 5 V rail. The 1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the thermal requirements of the QSOP-16 package meet the application's dissipation needs under maximum load conditions.
Part Context
The EL7562 belongs to the EL756x series of power management ICs from Renesas (formerly Intersil). This series focuses on high-efficiency step-down conversion for low-voltage digital applications. The CUZ suffix typically denotes a lead-free, halogen-free variant in a specific plastic package format.
Replacement Considerations
Consult the official Renesas EL7562 datasheet for direct pin-compatible substitutes within the same family. Cross-reference with other synchronous buck regulators offering similar 2 A output and 1 MHz frequency if the EL7562CUZ is unavailable.
