IR3596 Datasheet | International Rectifier

  Digital Multi-Phase Memory/Mobile Controller Features - Ultra Low Power single loop PWM Controller with 3 PWMs configurable as 1, 2, 3 phase systems - pliant with Intel VR12.5 Rev 1.3/VR12.6 Rev1.0 specifications - Intel® VR12.5/VR12.6 SVID or I2C controlled regulation - Optimized for 3 phase DDR memory solution when paired with IR3548 and IR355x Pow IRstage - ~50m W @ Maximum Performance - patible with Active Tri Level (ATL) Industry Standard Tri-state Drivers - Dynamic Phase Control and Automatic Power State Switching with Active Diode Emulation for Very Light Loads - I2C system interface for telemetry of Temperature, Voltage, Input and Output Current & Power - Fault Protection: Output OVP, UVP, OC Warn, OCP, OT Warn, OTP - IR Adaptive Transient Algorithm (ATA) minimizes output bulk capacitors and system cost - 8 Time Programming (MTP) with integrated charge pump for easy custom configuration - 200k Hz to 2MHz switching frequency per phase - +3.3V supply voltage; -40°C to 85°C ambient operation - Pb-Free, Ro HS, 4x4mm, 28-pin, 0.4mm pitch QFN DESCRIPTION The IR3596 is a flexible single loop digital multi-phase buck controller that can be configured as a 1, 2 or 3 phase system when bined with IR Dual 6x8mm IR3548 or IR355x pow IRstages. Power consumption is minimized while maintaining full digital capability and flexibility. Digital non-linear transient control allows lower frequency operation to achieve the highest efficiency possible while providing minimal all ceramic output capacitor solutions. The IR3596 includes IR’s Efficiency Shaping Technology to automatically deliver exceptional efficiency at minimum cost across the entire load range and can be configured to enter 1-phase operation and active diode emulation mode automatically or by mand. The IR3596 may also shut down connected drivers/Pow IRstage to minimize the quiescent current consumption in the system to maximize battery life on next gen VR12.5/VR12.6 notebooks/Ultrabooks. IR’s...
