Servers and High End Desktop CPU VRs for non-core applications Telecom & Datacom Applications Distributed Point of Load Power Architectures Product validation Qualified for industrial applications according to the relevant tests of JEDEC47/20/22 Final Datasheet Please read the Important Notice and Warnings at the end of this document V2.2 www.infineon.com page 1 of 64 Feb 6 2019 Description The IR38164 OptiMOS IPOL is an easy to use, fully integrated and highly efficient dc-dc regulator with Intel SVID and I2C/PMBus interfaces. The on-chip PWM controller and co-packaged low duty cycle optimized MOSFETs make the device a space-efficient solution, providing accurate power delivery for low output voltage and high current applications that require an Intel SVID interface. The IR38164 offers programmability of switching frequency, output voltage, and fault/warning thresholds and fault responses while operating over a wide input range. Providing flexibility as well as system level security in the event of fault conditions. The switching frequency is programmable from 500 kHz to 1.5 MHz for an optimum solution. The on-chip sensors and ADC along with the SVID, I2C and PMBus make it easy to monitor and report input voltage, output voltage, output current and temperature. Final Datasheet 2 of 64 V2.2 Feb 6 2019
