The ISL99227 and ISL99227B are Smart Power Stage (SPS) compatible with Intersil’s 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. Light-load efficiency is supported via a dedicated LFET control pin. An industry leading thermally enhanced 5x5 PQFN package allows minimal overall PCB real estate. The ISL99227 and ISL99227B feature a 3. 3V compatible, 5. 0V compatible tri-state PWM input that, working together with Intersil’s multiphase PWM controllers, provide a robust solution in the event of abnormal operating conditions. The ISL99227 and ISL99227B also improve 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.
