DCDC Converter OptiMOS IPOL Single-input Voltage, 30A Buck Regulators with PVID IR38265 FEATURES DESCRIPTION Internal LDO allows single 16V operation This family of OPTIMOS IPOL devices offers easy-to-use, Output Voltage Range: 0.5V to 0.875*PVin fully integrated and highly efficient DC/DC regulators with 0.5% accurate Reference Voltage PVID and I2C interface. The on-chip PWM controller and co- Enhanced line/load regulation with Feedforward packaged low duty cycle optimized MOSFETs make these Frequency programmable by I2C up to 1.5 MHz devices a space-efficient solution, providing accurate power Enable input with Voltage Monitoring Capability delivery for low output voltage and high current Remote Sense Amplifier with True Differential applications that require a parallel VID interface. Voltage Sensing 3 pins (PVID) to program output voltage These versatile devices offer programmability of switching Fast mode I2C interface for programming, frequency, output voltage, and fault/warning thresholds sequencing and margining output voltage, and for and fault responses while operating over a wide input monitoring input voltage, output voltage, output range. Thus, they offer flexibility as well as system level current and temperature. security in event of fault conditions. I2C configurable fault thresholds for input UVLO, output OVP, OCP and thermal shutdown. The switching frequency is programmable from 150 kHz to Thermally compensated pulse-by-pulse current limit and Hiccup Mode Over Current Protection 1.5 MHz for an optimum solution. Dedicated output voltage sensing for power good indication and overvoltage protection which The on-chip sensors and ADC along with the PVID and I2C remains active even when Enable is low. interfaces make it easy to monitor and report input voltage, Enhanced Pre-Bias Start up output voltage, output current and temperature.
