DCDC Converter OptiMOS IPOL Single-input Voltage, 15 A & 30 A Buck Regulators with SVID IR38163/363/165/365 FEATURES DESCRIPTION Internal LDO allows single 16 V operation Output Voltage Range: 0.5 V to 0.875*PVin This family of Op tiMO S IPOL devices offers easy-to-use, 0.5% accurate Reference Voltage fully integrated and highly efficient DC/DC regulators with Intel VR12.5 (Rev 1.5) VR13 (Rev 1.0) and SVID Intel SVID and I2C/PM Bu s interface. The on-chip PWM (Rev 1.7) compliant controller and co-packaged low duty cycle optimized Enhanced line/load regulation with Feedforward MOSFETs make these devices a space-efficient solution, Frequency programmable by PMBu s up to 1.5 providing accurate power delivery for low output voltage MHz and high current applications that require an Intel SVID Enable input with Voltage Monitoring Capability interface. Remote Sense Amplifier with True Differential Voltage Sensing Fast mode I2C and 400 kHz PMBu s interface for These versatile devices offer programmability of switching programming, sequencing and margining output frequency, output voltage, and fault/warning thresholds voltage, and for monitoring input voltage, output and fault responses while operating over a wide input voltage, output current and temperature. range. Thus, they offer flexibility as well as system level PMBu s configurable fault thresholds for input security in event of fault conditions. UVLO, output OVP, OCP and thermal shutdown. Thermally compensated pulse-by-pulse current The switching frequency is programmable from 150 kHz to limit and Hiccup Mode Over Current Protection 1.5 MHz. Dedicated output voltage sensing for power good indication and overvoltage protection which remains active even when Enable is low. The on-chip sensors and ADC along with the SVID and Enhanced Pre-Bias Start up PMBu s interfaces (IR18163 and IR38363) or SVID and I2C Integrated MOSFET drivers and Bootstrap diode interfaces (IR38165 and IR38365) make it easy to monitor o o Operating junction temp: -40 C<Tj<125 C and report input voltage, output voltage, output current Thermal Shut Down and temperature.
