Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL8500IRZ

ISL8500IRZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8500IRZ is a discontinued high-performance standard buck PWM regulator from Renesas Electronics Corporation. It integrates a 2A switching power MOSFET with voltage mode control and input voltage feed forward. The device supports a fixed 5V or variable 5.5V to 25V input range, generating an adjustable output voltage from 0.6V to 19V with continuous current up to 2A. It operates at a fixed 500kHz switching frequency and includes protection features such as overcurrent, undervoltage, and thermal overload protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a 2A standard buck PWM controller and internal N-Channel power MOSFET optimized for thermal performance.
Utilizes voltage mode control with input voltage feed forward to minimize solution size and component selection complexity.
Includes integrated protection mechanisms for overcurrent, undervoltage, and thermal overload conditions.

Voltage Regulators - DC DC Switching Regulators Applications

General purpose WLAN cards including PCMCIA, Cardbus32, and MiniPCI formats
Compact Flash card interfaces
Hand-held instruments
LCD panel power supplies
Set-top box applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the obsolete status of the ISL8500IRZ before procurement planning. As this component is no longer in production, availability is limited to existing stock or surplus channels. Confirm package integrity and RoHS compliance upon receipt. Evaluate alternative sources carefully to ensure authenticity and storage history validity.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select the ISL8500IRZ for point-of-load applications requiring a simple, single-chip buck solution with integrated switching capability. It is suitable for designs needing an adjustable output voltage within the specified range and fixed 500kHz operation. Consider the discontinuation status when designing new products; prioritize newer series like the ISL85003 for long-term supply chain stability.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL8500 belongs to the legacy Intersil/Renesas portfolio of standard buck regulators. It serves as a foundational component for low-power DC/DC conversion, bridging older design architectures with modern efficiency requirements. This specific part number represents the RoHS-compliant version of the original ISL8500 controller.
