Overview
The EL7532IY is a synchronous, integrated FET 2A step-down regulator with internal compensation. It operates with an input voltage range from 2.5V to 5.5V, accommodating supplies of 3.3V, 5V, or a single Li-Ion battery source. The output can be externally set from 0.8V to VIN with a resistive divider. The device features PWM mode control and typically operates at a switching frequency of 1.5MHz. Additional features include a 100ms Power-On-Reset output, less than 1µA shut-down current, short-circuit protection, and over-temperature protection. It is available in the 10-pin MSOP package.
Feature Summary
- Synchronous rectification for high efficiency
- Internal loop compensation simplifies design
- Low shutdown current consumption
- Integrated thermal and short-circuit protection
Applications
- PDA and pocket PC computers
- Portable instruments
- Li-Ion battery powered devices
- ASiC/FPGA/DSP supplies
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity upon receipt. Check datasheet revisions for any parameter updates. Ensure storage conditions meet moisture sensitivity level requirements. Validate compatibility with existing circuit designs before implementation.
Selection Notes
Consider input voltage range compatibility with system power sources. Evaluate output current requirements against the 2A limit. Assess PCB space constraints given the small package size. Review thermal management needs for continuous operation. Verify external component availability for setting output voltage.
Part Context
Part of Renesas' EL7532 series of monolithic step-down regulators. Designed for portable applications requiring efficient power conversion. Offers compact solution with minimal external components. Provides reliable performance across wide temperature ranges.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Evaluate newer generations with improved efficiency or packaging. Consider functional equivalents from other manufacturers if supply chain issues persist.
