DATASHEET

Smart Power Stage (SPS) Module with Integrated High

Accuracy Current and Temperature Monitors

ISL99227, ISL99227B

Features

The ISL99227, ISL99227B are Smart Power Stages (SPS)

compatible with Intersil’s ISL68xxx/69xxx Digital Multiphase

(DMP) controllers and phase doubler (ISL6617A), respectively.

The ISL99227, 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.

• Input range: +4.5V to +18V

• Supports 60A DC current

• ISL99227 with 3.3V compatible tri-state PWM input

• ISL99227B with 5.0V compatible tri-state PWM input

• Downslope current sensing

• ±3% accuracy current monitor (IMON) with REFIN input

• 8mV/°C temperature monitor with OT flag

• Dedicated low-side FET control input

• Comprehensive fault protection for high system reliability

- High-side FET short and overcurrent protection

- Over-temperature protection

The ISL99227, ISL99227B feature a 3.3V compatible, 5.0V

compatible tri-state PWM input that, working together with

Intersil’s multiphase PWM controllers, will provide a robust

solution in the event of abnormal operating conditions. The

ISL99227, ISL99227B also improve system performance and

reliability with integrated fault protection of UVLO,

- V and V Undervoltage Lockout (UVLO)

• Open-drain fault reporting output

• Up to 2MHz switching frequency

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.

• Pb-free (RoHS compliant), 32 Ld 5x5 PQFN

Applications

• High frequency and high efficiency VRM and VRD

• Core, graphic and memory regulators for microprocessors

• High density VR for server, networking and cloud computing

• POL DC/DC converters and video gaming consoles
