ISL99360, ISL99360B
Smart Power Stage (SPS) with Integrated High Accuracy Current and
Temperature Monitors
Data Short
To request the full datasheet, visit the ISL99360, ISL99360B product pages.
The ISL99360 and ISL99360B are Smart Power
Stages (SPS) compatible with the ISL68xxx/69xxx
Digital Multiphase (DMP) controllers and phase
doubler (ISL6617A), respectively. The ISL99360 and
ISL99360B 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 ISL99360 and ISL99360B feature a 3.3V
compatible, 5.0V compatible tri-state PWM input that
works together with the Renesas multiphase PWM
controllers to provide a robust solution in abnormal
operating conditions. The ISL99360 and ISL99360B
also improve system performance and reliability with
integrated fault protection of UVLO, HFET short,
over-temperature, and overcurrent. An open-drain
fault reporting pin simplifies the handshake between
the SPS and controllers and can disable the controller
during start-up and fault conditions.
