ISL99227BFRZ-TR5782

Overview

The ISL99227BFRZ-TR5782 is a Smart Power Stage (SPS) module from Renesas Electronics, integrating high-side and low-side power switches with gate drivers into a single PQFN-32 package. It supports an input voltage range of 4.5 V to 18 V and delivers up to 60 A output current. The device operates within a temperature range of -40°C to +85°C and features a maximum output voltage capability of 3.3 V. Designed for high-frequency operation, it serves as a key component in point-of-load (POL) DC/DC converters for processors, graphics, and memory regulators.

Feature Summary

• Integrates high-accuracy current sensing with integrated temperature compensation for precise load regulation.
• Supports diode emulation mode to enhance efficiency during light-load conditions.
• Includes comprehensive fault management features such as pulse-by-pulse phase current limiting and total output current protection.

Applications

• Core, Graphic, and Memory Regulators for Microprocessors
• High Frequency and High Efficiency VRM and VRD Systems
• High Density VR for Server, Networking, and Cloud Computing
• Point-of-Load (POL) DC/DC Converters
