50A Integrated PowIRstage IR3556 FEATURES DESCRIPTION Integrated driver, Schottky diode, control The IR3556 integrated PowIRstage contains a MOSFET and synchronous MOSFET synchronous buck gate driver IC which is co-packed with control and synchronous MOSFETs and a 5mV / A on-chip MOSFET current sensing Schottky diode to further improve efficiency. The with temperature compensated reporting package is optimized for PCB layout, heat transfer, Input voltage (VIN) range of 4.5V to 15V driver/MOSFET control timing, and minimal switch node VCC and VDRV supply of 4.5V to 7V ringing when layout guidelines are followed. The paired gate driver and MOSFET combination enables higher Output voltage range from 0.25V up to 5.5V efficiency at lower output voltages required by cutting Output current capability of 50A edge CPU, GPU, ASIC and DDR memory designs. Operation up to 1.0MHz The IR3556 PowIRstage internal MOSFET current VCC under voltage lockout (UVLO) sense algorithm with integrated temperature o 8mV / C temperature analog output and compensation achieves superior current sense thermal flag pull-up to 3.3V accuracy vs. best-in-class controller based Inductor DCR sense methods. Other features include Over temperature protection (OTP) preliminary overvoltage protection and flag, internal Cycle-by-cycle self-preservation over current cycle-by-cycle self-preservation over current protection protection (OCP) and flag, phase fault flag, over temperature protection and flag, and internal package temperature reporting. MOSFET phase fault detection and flag Preliminary overvoltage protection (Pre-OVP) Up to 1.0MHz switching frequency enables high Compatible with 3.3V tri-state PWM Input performance transient response, allowing miniaturization of output inductors, as well as input and Body-Braking load transient support output capacitors while maintaining industry leading through PWM Tri-state efficiency. Diode emulation mode (DEM) for improved light load efficiency When combined with IRs digital controllers, the IR3556 Efficient dual sided cooling incorporates the Body-Braking feature through PWM tri-state which enables reduction of output capacitors. Small 6mm x 6mm x 0.9mm PQFN package Synchronous diode-emulation mode is also supported Lead free RoHS compliant package through a built-in ZCD EN enabled zero-cross detect circuit in the IR3556 which increases system light-load efficiency. APPLICATIONS The IR3556 is optimized for CPU core power delivery in High frequency, high current, low profile DC- server applications. The ability to meet the stringent DC converters requirements of the server market also makes the Voltage Regulators for CPUs, GPUs, ASICs, IR3556 ideally suited for powering GPU, ASIC, DDR and DDR memory arrays memory, and other high current designs.
