-  The XDP720 is an eFuse with integrated current sensor and digital
-  controller. It provides accurate system telemetry (V, I, P, T) and
-  reports analog current at the IMON pin for post-processing.
+  The XDP720 and XDP730 are PMBus-compliant digital eFuse controllers
+  with an integrated current sensor.  They provide accurate system
+  telemetry (V, I, P, T) and report analog current at the IMON pin for
+  post-processing.

+  Both parts share the same PMBus register map and direct-format
+  coefficients; they differ in the GIMON gain step exposed via the
+  TELEMETRY_AVG register (bit 10) and in the VDD_VIN pin number
+  (XDP720: pin 9, XDP730: pin 20).
