ISL9104IRUWZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9104IRUWZ-T7A is a synchronous buck converter from the Renesas ISL9104 series, packaged in a 6-UTDFN (1.6x1.6 mm) footprint. It operates with an input voltage range of 2.7 V to 6 V and provides a fixed output voltage of 1.2 V at a maximum output current of 500 mA. The device utilizes a high switching frequency of 4.3 MHz to enable the use of small external components. It functions within an operating temperature range of -40 °C to +85 °C.

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 moisture sensitivity level is MSL 1. Ensure compatibility with existing PCB layouts given the specific 6-UTDFN dimensions. Review manufacturer notices for any label or packaging changes prior to integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 1.2 V output is required without external programming resistors. The 4.3 MHz frequency supports miniaturization compared to lower-frequency alternatives. Consider the 500 mA current limit against peak load demands. Evaluate thermal performance within the specified ambient temperature range for the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the ISL9104 family of low IQ synchronous buck converters. It shares architectural similarities with variants offering different fixed output voltages, such as 1.5 V or 1.8 V options. The series is designed for applications prioritizing space constraints and moderate current delivery from single-cell lithium-ion sources.
