Overview
The EL7534IY is a monolithic synchronous step-down regulator featuring integrated power FETs and internal compensation. It supports an input voltage range of 2.5V to 5.5V with a maximum output current of 600mA. The device operates at a fixed switching frequency of 1.2MHz, enabling the use of small external components. It provides adjustable output voltages from 0.8V to 5.5V. The component is housed in a 10-lead MSOP package and is rated for operation between -40°C and +85°C.
Feature Summary
- Synchronous architecture with integrated high-side and low-side power FETs
- Internal compensation network simplifies external component selection
- Fixed 1.2MHz switching frequency minimizes passive component size
- Integrated enable pin allows precise power sequencing control
Applications
- Portable battery-powered equipment
- Point-of-load regulation for digital signal processors
- Embedded systems requiring compact power solutions
- Industrial control modules
Procurement Notes
Verify the specific suffix (e.g., IY vs IYZ) against the manufacturer's current datasheet to confirm package type and temperature rating. Confirm availability status as older Intersil part numbers may have limited stock or be subject to discontinuation notices. Ensure the ordering code matches the required tape-and-reel or tube packaging format.
Selection Notes
Select this component when a compact, single-output buck converter is needed for inputs up to 5.5V. The internal compensation reduces design complexity compared to non-compensated regulators. Consider the 600mA limit for load requirements and the 1.2MHz frequency for trade-offs between efficiency and filter size. Verify thermal performance within the MSOP package for the expected ambient conditions.
Part Context
This part belongs to the EL7534 series of synchronous step-down regulators manufactured by Renesas/Intersil. It is designed for applications requiring high efficiency and minimal footprint. The series typically includes variants with different packages such as MSOP and QFN, offering flexibility for various PCB layout constraints while maintaining consistent electrical performance characteristics.
Replacement Considerations
Check for direct equivalents like the EL7534IYZ-T7 or EL7534IRE-T13 for package variations. Verify that substitute parts maintain the same 600mA current rating and 1.2MHz frequency. Ensure compatibility with existing PCB footprints if changing from MSOP to other package types.
