ISL99227BFRZ-T Smart Power Stage (SPS) Module The ISL99227B is Smart Power Stage (SPS) compatible with ISL68xxx / ISL69xxx Digital Multiphase (DMP) controllers and phase doubler (ISL6617A), respectively. The ISL99227B has 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. Light-load efficiency is supported through a dedicated LFET control pin. 

The ISL99227B features 5.0V compatible tri-state PWM input. The ISL99227B also improves system performance and reliability with integrated fault protection of UVLO, over-temperature, and overcurrent. An open-drain fault reporting pin simplifies the handshake between SPS and Intersil controllers and can be used to disable the controller during start-up and fault conditions.
