-   The ADP1050 is used to monitor system voltages, currents and temperatures.
+   The ADP1050, ADP1051, and ADP1055 are used to monitor system voltages,
+   currents, power and temperatures.
+
    Through the PMBus interface, the ADP1050 targets isolated power supplies
    and has four individual monitors for input/output voltage, input current
    and temperature.
