ISL9104IRUFZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9104IRUFZ-T7A is a synchronous buck converter IC manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 2.7V to 6V and provides a fixed output voltage of 2.5V at a maximum current of 500mA. The device utilizes a switching frequency of 4300 kHz (4.3 MHz) for efficient power conversion. It is housed in a surface-mount UTDFN-6 package measuring 1.6mm x 1.6mm with a height of 0.5mm. The component supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T7A' indicates tape and reel packaging when sourcing. Confirm the fixed 2.5V output variant matches the circuit requirements, as other output voltages exist within the ISL9104 family. Ensure the UTDFN-6 footprint aligns with the PCB layout specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for applications requiring a fixed 2.5V rail from a 2.7V to 6V source. The 4.3MHz frequency allows for smaller external passive components compared to lower-frequency regulators. Verify that the 500mA load current does not exceed the thermal limits of the 1.6x1.6mm package in the intended enclosure environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the ISL9104 series of low IQ, high-efficiency synchronous buck converters. The series is designed for compact portable electronics. The IRUFZ-T7A designation specifies the 2.5V fixed output version in the T7A tape and reel packaging format, distinct from adjustable or other fixed voltage variants in the same product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

ISL9104AIRUCZ-T7A offers a similar form factor but provides a fixed 1.8V output instead of 2.5V. ISL9104IRUAZ-T7A is an adjustable voltage variant within the same package. Direct replacement requires matching the specific output voltage requirement of the target application.
