ISL99227FRZ-T Integrated High-Accuracy Controller PWM Interface
32-PQFN
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 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.
