EL7536IY

Overview

The EL7536IY is a monolithic synchronous step-down switching regulator manufactured by Renesas Electronics Corporation. It features an integrated 1A power stage and internal compensation, simplifying design requirements. The device operates with an input voltage range of 2.5V to 5.5V, making it suitable for 3.3V and 5V systems or lithium-ion battery applications. The adjustable output voltage ranges from 0.8V to the input voltage level. It utilizes PWM control with a typical switching frequency of 1.4MHz. The component is housed in a 10-lead MSOP package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 1A synchronous power stage with internal compensation to minimize external component count.
• Supports wide input voltage ranges compatible with standard 3.3V, 5V, and lithium-ion power sources.
• Includes protection mechanisms such as thermal shutdown and a 100ms power-on reset function.

Applications

• Portable consumer electronics powered by single-cell lithium-ion batteries
• Embedded systems requiring efficient 3.3V or 5V regulation
• Industrial control modules operating within standard voltage rails

Procurement Notes

Verify current availability status as this component may be subject to end-of-life notifications or limited supply constraints. Confirm that the specific package variant matches the target PCB footprint. Ensure compliance with RoHS directives if required for the final assembly. Cross-reference datasheet revisions to confirm pinout consistency before integration into new designs.

Selection Notes

Select this regulator when a compact solution with high efficiency is required for low-power applications. The internal compensation reduces layout sensitivity compared to non-compensated alternatives. Consider the 1A output limit against peak load demands. The fixed switching frequency aids in EMI filtering design. Evaluate the MSOP package size against available board space constraints.

Part Context

The EL7536 belongs to the EL753x series of synchronous buck regulators from Renesas. This family targets portable and industrial applications needing small form factors. Similar parts in the series include the EL7530 and EL7532, which offer different current capabilities. The EL7536 specifically balances 1A output with a compact 10-lead MSOP package for space-constrained designs.
