Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL9103IRUCZ-T

ISL9103IRUCZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9103IRUCZ-T is a synchronous buck converter from the Renesas ISL9103 series, housed in a uTDFN-6 package. It operates with an input voltage range of 2.7 V to 6 V and provides a fixed 1.8 V output at up to 500 mA. The device utilizes a 2.4 MHz PWM switching frequency and achieves high efficiency through integrated synchronous rectification. Key electrical characteristics include a quiescent current of 20 µA in skip mode and less than 1 µA in shutdown. It features internal digital soft-start, peak current limiting, short circuit protection, and over-temperature protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous buck regulator topology for high efficiency
Logic-controlled shutdown with ultra-low standby current consumption
Internal digital soft-start mechanism to limit inrush current
Comprehensive protection suite including over-temperature and short-circuit safeguards

Voltage Regulators - DC DC Switching Regulators Applications

Portable handheld devices
Wireless communication equipment
Battery-powered consumer electronics

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity upon receipt as the unit utilizes a small footprint uTDFN-6 configuration. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Cross-reference ordering information with official Renesas documentation to validate suffix designations and revision history before integration into production schedules.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing compact power systems requiring low quiescent current and fixed voltage regulation. The 2.4 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the required output voltage matches the fixed 1.8 V option available in this specific part number variant. Consider thermal performance within the uTDFN-6 package for the intended load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9103 family of low IQ synchronous buck converters manufactured by Renesas Electronics. The series is designed for portable applications where battery life and board space are critical constraints. The ISL9103IRUCZ-T specifically denotes the industrial temperature grade version with a fixed 1.8 V output, distinguishing it from adjustable or other voltage variants within the same product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers. Verify compatibility regarding pinout, electrical specifications, and thermal characteristics before substitution.
