... Conduction Mode (BCM) also called Critical Conduction Mode. Dynamic Self−Supply (DSS): due to its Very High Voltage Integrated Circuit (VHVIC) technology, ON Semiconductor’s NCP1207 allows for a direct pin connection to the high−voltage DC rail. A dynamic current source charges up a capacitor and thus provides a fully independent V level to the NCP1207 ...

Latching Off the NCP1207 In certain cases, it can be very convenient to externally shut down permanently the NCP1207 via a dedicated signal, e.g. coming from a temperature sensor. The reset occurs when the user unplugs the power supply from ...
