Power Input

Power to the PAC5532EVK1 evaluation module can be applied to the VIN and GND spade connectors. Said

applied power should not exceed 160V (Abs Max).

The PAC5532EVK1 is optimized to operate with voltages ranging from 25V to 120V Nominal (160V Abs Max).

When the VIN input voltage goes above 25V, the system exits UVLO protection and all subsystems, including

voltage regulators, analog front end and microcontroller, are enabled.

When an operational voltage is applied, LED D5 will light up. This is the LED which notifies that the VSYS

(5V) rail is up and running. VP (12V gate drive), 3.3V (for analog circuitry) and 1.2V (for CPU core) regulators

will also be operating at this point in time. The module is now ready for use.

The following table shows the available LEDs and their associated diagnostic function.
