#FIG_Z3J_FHK_2MB to #FIG_CVJ_JNM_JWB show the output voltage start-up waveforms at 12-V input and –8-V output with the converter starting up into no load and into 2.7-A constant-current load using the electronic load. Two methods of enabling the converter were exercised and captured: one where the input voltage is already turned ON and the converter waits for the enable signal to go HIGH; the other where the enable signal is tied to VIN and the converter waits for the main power supply to be turned ON.
