IR3590BMTRPBF

Digital Multi-Phase Redundant Controller FEATURES IR3590B DESCRIPTION  6-phase single loop configurable PWM Controller  Serial I2C control for Vout changes  Programmable Constant Current Protection  Dead-phase Protection and Flag  Min/Max Telemetry registers and real-time monitoring via I2C (IIN, VIN, IOUT, VOUT, Temp)  Improved Min/Max Telemetry Resolution  Programmable 1-phase or 2-phase for Light Loads and Active Diode Emulation for Very Light Loads  IR Adaptive Transient Algorithm (ATA) minimizes output bulk capacitors and system cost The IR3590B is a 6-phase digital, single loop, multiphase buck controller with a feature set optimized to support redundant power supply systems. The IR3590B includes IR’s Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. IR Variable Gate Drive optimizes the MOSFET gate drive voltage based on real-time load current. IR’s Dynamic Phase Control adds/drops phases based upon load current. The IR3590B can be configured to enter 1-phase operation and active diode emulation mode automatically or by command. IR’s unique Adaptive Transient Algorithm (ATA), based on proprietary non-linear digital PWM algorithms, minimizes output bulk capacitors, and improves transient response and form factor.  IR Efficiency Shaping Features including Variable Gate Drive and Dynamic Phase Control  Auto-Phase Detection with auto-compensation  Fault Protection: Output OVP, UVP, OC Warn, OCP, OT Warn, OTP  Increased Iccmax range to 510A.  Multiple Time Programming (MTP) with integrated charge pump for easy custom configuration  Compatible with IR ATL and 3.3V tri-state Drivers The I2C interface can communicate with up to 127 IR3590B-based VR loops. Device configuration and fault parameters are easily defined using the IR PowIRcenter GUI and stored in on-chip MTP. MTP storage saves pins and enables a small package size. The IR3590B extensive fault protection includes output OV, UV and OC protection, a thermistor based OT protection input with a VRHOT signal output, and a selectable and separate Over Current warning flag through the ALERT#.  200kHz to 2MHz switching frequency per phase  +3.3V supply voltage; -40°C to 85°C Ambient  Pb-Free, Halogen Free, RoHS, 5x5mm, 40-pin, 0.4mm pitch QFN APPLICATIONS  Supports Phase Redundant based Server systems  Server CPU  Server Memory ORDERING INFORMATION Base Part Number Package Type IR3590B Standard Pack Orderable Part Number Form Quantity QFN 5 mm x 5 mm Tape and Reel 3000 IR3590BMxxyyTRP2 IR3590B QFN 5 mm x 5 mm Tape and Reel 3000 IR3590BMTRPBF1 IR3590B QFN 5 mm x 5 mm Tray 4900 IR3590BMTYPBF1 Notes: 1.
