Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL6273IRZ-T

ISL6273IRZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL6273IRZ-T is a synchronous step-down voltage regulator manufactured by Intersil, designed for low-voltage microprocessor applications. It features an integrated high-side and low-side MOSFETs within a compact DFN-EP-10 package. The device operates with a fixed switching frequency of 1.5 MHz and supports an output current of 1.2 A. The adjustable output voltage range spans from 800 mV to 5.5 V. It functions reliably across an operating temperature range of -40°C to +85°C. This component is classified as a single-output buck converter suitable for portable electronic devices.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates high-side and low-side power FETs for high efficiency in a small footprint
Fixed 1.5 MHz switching frequency enables the use of compact external components
Low quiescent current operation optimizes battery life in portable systems

Voltage Regulators - DC DC Switching Regulators Applications

Powering low-voltage microprocessors in PDAs
Power supply stages for cellular phones
Compact portable electronic devices requiring efficient step-down regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the 'RZ' tube variant when sourcing replacements. Confirm that the component remains End-of-Life (EOL) status with Renesas/Intersil before finalizing design-in decisions. Ensure compatibility with existing PCB footprints for the 10-pin DFN-EP package. Check for moisture sensitivity levels if storage conditions have been uncontrolled.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator for designs prioritizing space savings due to its integrated FET architecture. The 1.5 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Ensure the load current does not exceed the 1.2 A continuous rating. Consider thermal dissipation requirements given the small DFN-EP-10 package size and exposed pad thermal characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL6273 series belongs to Intersil's portfolio of low quiescent current synchronous buck regulators. These components were specifically engineered to meet the power density demands of mobile communication devices and handheld computing platforms. The IRZ-T designation specifies the reel-packaged version of the standard ISL6273IRZ component.
