ISL99227BFRZ-T Cu 32L QFN INTERSIL PMIC 5V PWM SPS Module

1.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 through 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 withIntersil’s multiphase PWM controllers, provide a robustsolution in the event of abnormal operating conditions. TheISL99227 and ISL99227B also improve system performanceand reliability with integrated fault protection of UVLO,over-temperature, and overcurrent. An open-drain faultreporting pin simplifies the handshake between SPS andIntersil controllers and can be used to disable the controllerduring start-up and fault conditions.
