This family of OptiMOSTMIPOL devices offers easy-to-use, fully integrated and highly efficient DC-DC regulators with Intel SVID and I2C/PMBus interface. The on-chip PWM controller and co-packaged low duty cycle optimized MOSFETs make these devices a space-efficient solution, providing accurate power delivery for low output voltage and high current applications that require an Intel SVID interface. These versatile devices offer programmability of switching frequency, output voltage, and fault/warning thresholds and fault responses while operating over a wide input range. Thus, they offer flexibility as well as system level security in event of fault conditions. The switching frequency is programmable from 150 kHz to 1.5 MHz for an optimum solution. The on-chip sensors and ADC along with the SVID and PMBus interfaces (IR38163 and IR38363) or SVID and I2C interfaces (IR38165 and IR38365) make it easy to monitor and report input voltage, output voltage, output current and temperature.
