OptiMOS™ IPOL DC-DC converter single-input voltage, 30 A buck regulators with PVID The IR38265 is a fully integrated, highly efficient DC-DC regulator with I2C and parallel VID interface (PVID). It offers programmability of switching frequency, output voltage, and fault/warning thresholds and fault responses. The on-chip sensors and ADC along with the PVID and I2C interfaces make it easy to monitor and report input voltage, output voltage, output current and temperature.
