* 1. Voltage is detected at the output terminals. * 2. OVP is activated even when V-LIMIT (voltage limit) is selected. The OVP activation point is approximately ±120 % of rtg. * 3. Peak current at 120 Apeak can be output for 10 ms with the CC mode response set to 1 ms. For other CC mode response settings, the peak current is limited (I.LIM) according to the specified response.
