Vin = 12 V, Vout = 1.5 V, Iout = 80 A. With the recommended capacitors (See Note 1) across the output, the output voltage stays within the load regulation window for all loads and transient events, up to 80 A. It will also allow instantaneous VID-on-the-fly changes of up to 500 mV at 80 A. VRM64 uses a five phase buck topology. Each phase switches at 830 kHz. This gives an equivalent switching frequency of 4.2 MHz Maximum current requires adequate forced air over the converter. Please consult Figure 1 for thermal derating. When the VRM detects an output over-voltage event, the OVP pin transitions to logic high. This signal can be used to shut down the supply to the VRM, or drive an external crowbar device. TYP 12 A 1600 μF 7 NOTES AND CONDITIONS Vin = Vin (typ.), Iout (cont.) = 80 A, VID = 1.5 V These are default settings. The current limit may be set to ‘trip’ or ‘hiccup’. The output overvoltage limits, input overvoltage and undervoltage settings, the output droop and offset, the current limit setpoint and many others can be changed by component changes. Please consult the factory for details. 8 0.01 G2/Hz from 5 Hz to 20 Hz, maintaining 0.02 G2/Hz from 20 Hz to 500 Hz, all axes. 9 In accordance with AMD requirements, PWRGD will go high at least 2 ms after VDD settles within specifications. 10 The ‘Y’ suffix indicates that these parts are TSE RoHS 5/6 (non Pb-free) compliant. Pb-free (RoHS 6/6) compliant versions may be available on special request, please contact your local sales representative for details. 11 NOTICE: Some models do not support all options.
