Overview
The EL7534IYZ is a monolithic step-down switching regulator IC manufactured by Intersil, now part of Renesas Electronics. It operates as a buck converter with an adjustable output voltage range from 0.8 V to 5.5 V and supports a maximum output current of 600 mA. The device integrates a high-side N-channel MOSFET and functions at a fixed switching frequency of 1.75 MHz. It accepts input voltages between 2.5 V and 5.5 V. The component is housed in a 10-lead MSOP package (0.118 inch width) and is rated for operation within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-side N-channel power switch for compact design
- Fixed 1.75 MHz switching frequency enables small external component size
- Adjustable output voltage via external resistor divider
- Includes internal compensation for stable loop performance
Applications
- Portable battery-powered equipment
- Point-of-load regulation modules
- Embedded systems requiring efficient DC-DC conversion
Procurement Notes
Verify the manufacturer status carefully, as Intersil has been acquired by Renesas Electronics. Confirm that the specific suffix 'IYZ' matches the required 10-MSOP package and industrial temperature grade. Check for end-of-life notifications or discontinuance notices, as older Intersil parts may have limited availability or require alternative sourcing strategies through authorized distributors.
Selection Notes
Select this component when a compact, single-output buck regulator is needed for inputs up to 5.5 V. Ensure the load current does not exceed 600 mA. Compare against the EL7535 series if higher current capability (350 mA vs 600 mA) or different voltage ranges are required. Verify that the 1.75 MHz frequency aligns with EMI constraints and inductor selection requirements for the target application.
Part Context
The EL7534IYZ belongs to the EL753x family of synchronous step-down regulators. It shares architectural similarities with the EL7535 but differs in output current capacity and specific electrical characteristics. This series was designed to provide efficient power management solutions for portable electronics before being integrated into Renesas's broader portfolio.
Replacement Considerations
Direct substitutes include the EL7534IYZ-T7 (tape and reel packaging variant). Other compatible options within the same family include the EL7535IYZ for applications requiring different current specifications, provided the pinout and control logic remain compatible.
