... EVAL6730 The over-current-protection limit is set but it can be changed by replacing the resistors R1 and R12 (see OCL and OCH pin). ● Vcc-Gndcc: Using the input voltage to supply the controller no power is required at this input. However the controller can be supplied separately from the power stage through the Vcc input (4.5- 14V) and, in this case, jumper G1 must be left open. ● ...
