MAX17039 Dual-Output, 3-Phase + 1 Phase Quick-PWM Controller for VR12/IMVP-7 The MAX17039 is a dual-output, step-down, constanton-time controller for VR12/IMVP-7 CPU core supplies. The controller consists of two high-current-switching power supplies for the CPU and GPU cores. The CPU regulator A is a three-phase constant-on-time architecture. The optional 3rd phase is configured with an external MAX8791 or MAX17491 driver. The second GPU regulator B is also a constant-on-time architecture with only single phase. Both regulators A and B include true differential voltage and current sensing to improve load-line and currentlimit accuracy. Switching frequencies are independently programmable, allowing 100kHz to 600kHz per phase operation. Output overvoltage protection OVP , undervoltage protection UVP , and thermal protection ensure effective and highly reliable operation. When any of these protection features detect a fault, the controller shuts down both channels. Regulator A includes transient-phase overlap, which speeds up the response time, reducing the total output capacitance. Regulator A also includes active overshoot suppression to further reduce the required output decoupling capacitance. Both controllers are fully compliant with Intel’s VR12/ IMVP-7 serial VID communication and control specifications. CPU and GPU outputs are controlled independently by writing the appropriate data into a function-mapped register file. A slew-rate controller allows controlled transitions between VID codes, controlled soft-start. The SVID interface also allows each regulator to be individually set into a low-power pulse-skipping state. Individual phases can be shut down based on the processors’ operating conditions to optimize efficiency. The MAX17039 is available in a lead-free, 56-pin, 7mm x 7mm TQFN package.
