IR38263 Datasheet | Infineon

Single-input Voltage, 30 A Buck Regulators with PVID DCDC Converter Opti MOS™ IPOL IR38263 Features - Internal LDO allows single 16 V operation - Output Voltage Range: 0.5V to 0.875- PVin - 0.5% accurate Reference Voltage - Enhanced line/load regulation with Feedforward - Frequency programmable by PMBus™ up to 1.5 MHz - Enable input with Voltage Monitoring Capability - Remote Sense Amplifier with True Differential Voltage Sensing - 3 pins (PVID) to program output voltage - Fast mode I2C and 400 k Hz PMBus™ interface for programming, sequencing and margining output voltage, and for monitoring input voltage, output voltage, output current and temperature. - PMBus™ configurable fault thresholds for input UVLO, output OVP, OCP and thermal shutdown. - Thermally pensated pulse-by-pulse current limit and Hiccup Mode Over Current Protection - Dedicated output voltage sensing for power good indication and overvoltage protection which remains active even when Enable is low. - Enhanced Pre-Bias Start up - Integrated MOSFET drivers and Bootstrap diode - Operating junction temp: -40o C<Tj<125o C - Thermal Shut Down - Post Package trimmed rising edge dead-time - PMBus™ Programmable Power Good Output - Small Size 5 mmx 7mm PQFN - Pb-Free (Ro HS pliant) - External resistor allows setting up to 16 PMBus™ addresses DESCRIPTION This family of Opti MOS™ IPOL devices offers easy-to-use, fully integrated and highly efficient DC/DC regulators with PVID 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 a parallel VID 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...
