Frequently Asked Questions
What does the PM7080ATR smart power stage integrate and how does that simplify PCB design?
PM7080ATR integrates high-side and low-side power MOSFETs together with their gate drivers and current sensing circuitry into a single package. This integration eliminates 4 to 6 discrete components per phase, reduces PCB area, lowers parasitic inductance in the switching loop, and simplifies layout for multi-phase synchronous buck converters powering sub-1 V processor core rails.
What switching frequency range is PM7080ATR designed for in CPU and FPGA power delivery?
PM7080ATR is designed for high-frequency synchronous buck operation, supporting switching frequencies in the range of several hundred kHz up to multiple MHz. Higher switching frequencies allow output inductors as small as 100 nH to 300 nH, enabling smaller and lighter voltage regulator modules in server and workstation motherboards with tight PCB height constraints.
How does PM7080ATR report current and temperature to a system power controller?
PM7080ATR provides analog or digital current sensing output alongside thermal reporting, allowing a companion PWM controller to perform per-phase current balancing and over-temperature protection. This telemetry eliminates the need for external sense resistors, reducing power loss and improving accuracy in multi-phase designs supplying 50 A or more to processor cores at 0.8 V to 1.8 V rails.
In which server or computing platforms is PM7080ATR typically deployed as a power stage component?
PM7080ATR is typically deployed in server CPU voltage regulator down (VRD) designs, FPGA core power modules, and GPU power delivery boards where each power stage phase delivers 20 A to 40 A of load current. Its compact form factor and integrated telemetry support densely populated multi-phase configurations with 4 to 12 phases on enterprise motherboards operating from a 12 V input bus.
