Test Connections
3 Test Connections
The board should be connected to a power supply and load as shown below in Figure 2. The EN post is
connected to the UVLO circuit on the back of the board. There is a resistive divider implemented on the
board that can be used to establish a precision UVLO level for the board that is currently set to 5.7V. A
common user change to this circuit is to adjust the value of RENT and RENB to adjust the operating
UVLO to that of the target application. Refer to the respective data sheet for calculation. Note that if in the
end application the EN pin voltage does not exceed 5.5V at maximum Vin, then the enable clamp zener
D1 can be omitted. (On revision A of the board the overlay for the zener diode has the cathode and anode
incorrectly labeled) Pull EN low to shutdown the module.
