Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL9103IRUJZ-T

ISL9103IRUJZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9103IRUJZ-T is a synchronous buck converter from the Renesas ISL9103 family, manufactured by Intersil (Renesas). It operates with a fixed 2.4 MHz PWM switching frequency and delivers a guaranteed output current of 500 mA. The device accepts an input voltage range of 2.7 V to 6.0 V and provides a fixed 1.8 V output. It features high efficiency up to 95%, low quiescent current of 20 µA in skip mode, and less than 1 µA shutdown current. The component utilizes a 6-pin uTDFN package measuring 1.6 mm x 1.6 mm.

Voltage Regulators - DC DC Switching Regulators Feature Summary

High-efficiency integrated synchronous buck regulator architecture
Ultrasonic switching frequency in skip mode to prevent audible noise
Internal digital soft-start with peak current limiting and short circuit protection
Logic-controlled shutdown with discharge output capacitor capability

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'IRUJZ' against official datasheets to confirm the fixed 1.8V output voltage and tape-and-reel packaging configuration. Confirm RoHS compliance status as indicated in manufacturer documentation. Ensure compatibility with the specified operating temperature range of -40°C to +85°C for your application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a compact solution with low standby power consumption. The fixed 2.4 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the required load current does not exceed the 500 mA guarantee and that the input supply remains within the 2.7 V to 6.0 V window.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9103 series of low IQ, high-efficiency synchronous buck converters designed for portable electronics. The series emphasizes miniaturization through small package options and low quiescent currents to extend battery life in mobile devices. The manufacturer transitioned from Intersil to Renesas Electronics Corporation during product lineage management.
