Overview
The EL7535IYZ-T13 is a synchronous, integrated FET 350mA step-down regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.5V to 6V and provides an adjustable output voltage from 800mV to 6V. The device utilizes PWM mode control with a typical switching frequency of 1.6MHz. Packaged in a 10-lead MSOP (MSOP-10) format, it supports surface mount installation. The component functions as a single-output DC-DC converter designed for portable applications.
Feature Summary
- Synchronous architecture with integrated power FETs for high efficiency
- Internally compensated design requiring minimal external components
- Includes short-circuit protection and over-temperature protection
Applications
- PDA and Pocket PC Computers
- Cellular Phones
- Portable Test Equipment
- Li-Ion Battery Powered Devices
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted or unavailable through major channels such as Mouser. Verification of current stock status and alternative sourcing strategies is required before procurement planning. Confirm final product discontinuance notifications directly with the supplier.
Selection Notes
Select this part for designs requiring a compact, low-current buck converter in a 10-lead MSOP package. Ensure the application input voltage falls between 2.5V and 6V. Verify that the 350mA output current requirement aligns with system loads. Note that the device is obsolete; evaluate replacement options if long-term supply stability is critical for the product lifecycle.
Part Context
The EL7535 series belongs to Renesas' portfolio of monolithic step-down regulators. These devices are characterized by their small footprint and internal compensation, allowing for simplified PCB layouts. The EL7535IYZ-T13 specifically denotes the tape-and-reel packaging variant of the standard EL7535IY IC, intended for automated assembly processes.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The EL7535IY-EVAL board serves as an evaluation tool rather than a direct functional replacement. Designers should consult official engineering support for recommended alternatives due to the EOL status.
