IR38164M
OptiMOS™ IPOL DC-DC converter single-input voltage, 30 A buck regulators with SVID
The IR38164M 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 IR38164M 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.
