Overview
The EL7536IY-T7 is a monolithic synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It integrates power FETs and operates in PWM mode with a typical switching frequency of 1.75 MHz. The device accepts an input voltage range of 2.5 V to 5.5 V and provides an adjustable output voltage from 800 mV to 5.5 V. It delivers a continuous output current of 1 A. The component is housed in a 10-lead MSOP package and is specified for operation over a temperature range of -40°C to +85°C.
Feature Summary
- Integrates synchronous internal FETs for high efficiency in a compact footprint
- Features fixed-frequency PWM control for stable regulation
- Includes built-in thermal protection and under-voltage lockout
Applications
- Portable test equipment
- Li-ion battery powered devices
- Small form factor modules
Procurement Notes
Verify the specific suffix T7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official datasheets as environmental declarations may vary by production batch. Check for End-of-Life (EOL) notices or Last-Time-Buy notifications directly from Renesas, as availability for this discontinued series is limited. Ensure moisture sensitivity level handling protocols are followed during assembly.
Selection Notes
Select this component for designs requiring a single-output 1 A buck converter with minimal external components. It is suitable for applications where board space is constrained due to the small MSOP package. Consider the 1.75 MHz switching frequency for trade-offs between inductor size and electromagnetic interference. Verify that the required output voltage falls within the 800 mV to 5.5 V adjustable range.
Part Context
This part belongs to the EL7536 family of monolithic step-down regulators. It shares architectural similarities with the EL7535 and EL7530 but offers higher output current capability. The EL7536 series is designed for portable electronics and battery-powered systems requiring efficient DC-DC conversion from standard 3.3 V or 5 V rails.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Renesas technical support for current recommended replacements for discontinued EL7536 variants.
