ISL99227, ISL99227B FN8684
Rev.3.00
Oct 2, 2017 Smart Power Stage (SPS) Module with Integrated High Accuracy Current and
Temperature Monitors
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. Features 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 …
