Overview

DATASHEET ISL99227, ISL99227B Smart Power Stage (SPS) Module with Integrated High Accuracy Current and Temperature Monitors The ISL99227 and ISL99227B are Smart Power Stage (SPS) compatible with the ISL68xxx/69xxx Digital Multiphase (DMP) controllers and phase doubler (ISL6617A), respectively.

The ISL99227 and ISL99227B have integrated high accuracy current and temperature monitors that can be fed back to the controller and doubler to complete a multiphase DC/DC system.

They simplify design and increase performance by eliminating the DCR sensing network and associated thermal compensation.

Key Features
