Overview
The EL7534IYZ-T7 is a monolithic synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.5 V to 5.5 V and delivers a maximum output current of 600 mA. The device features an adjustable output voltage ranging from 800 mV to 5.5 V. It integrates a fixed internal switching frequency of 1.5 MHz, enabling the use of small external components. The IC is housed in a 10-MSOP package and supports operation across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates synchronous rectification for high efficiency in a compact footprint.
- Utilizes a fixed 1.5 MHz switching frequency to minimize external passive component size.
- Features an adjustable output voltage capability within the specified operational limits.
Applications
- Portable battery-powered equipment requiring efficient DC-DC conversion
- Embedded systems utilizing single-cell lithium-ion power sources
- General-purpose low-voltage power distribution networks
Procurement Notes
Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance and moisture sensitivity level requirements prior to assembly. Review manufacturer Product Change Notifications for any historical revisions affecting pinout or electrical characteristics. Ensure supply chain stability as availability may be limited.
Selection Notes
Select this component when a compact, synchronous buck solution is required for inputs up to 5.5 V. The 1.5 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 600 mA output limit and MSOP-10 thermal constraints during PCB layout design.
Part Context
This part belongs to the EL7530/EL7534 family of monolithic switching regulators. These devices are designed for space-constrained applications requiring high efficiency. The EL7534 variant specifically offers synchronous rectification, distinguishing it from non-synchronous counterparts in the broader product line.
Replacement Considerations
Consult official documentation for direct substitutes. Verify that alternative parts match the 10-MSOP package, 600 mA current rating, and 1.5 MHz switching frequency. Ensure compatibility with existing control loop compensation and thermal management strategies.
