User guide for EVAL_38263-PVID1 evaluation board
The IR38263 OptiMOS iPOLTM is an easy-to-use, fully integrated and highly efficient DC/DC regulator with Intel
SVID and I2C/SMBus interface. The onboard PWM controller and low duty cycle optimized MOSFETs make
IR38263 a space-efficient solution, providing accurate power delivery for low output voltage and high current
IR38263 is a versatile regulator which offers programmability of switching frequency, output voltage, and
fault/warning thresholds and fault responses while operating over a wide input and output voltage range. Thus,
it offers flexibility as well as systemlevel security in event of fault conditions.
The switching frequency is programmable from166 kHz to 1.5 MHz for an optimum solution. The on-chip
sensors and ADC along with the SVID and PMBus interfacesmake it easy tomonitor and report input voltage,
output voltage, output current and temperature.
This user guide contains the schematic and bill ofmaterials for the EVAL_38263_PVID1 evaluation board. The
guide describes the use of the evaluation board itself. Detailed application information for IR38263 is available
in the IR38263 data sheet.
