Customer Specific Device from ON Semiconductor SCYW99143 Universal High Voltage Control Block for SMPS Controllers with Extremely Low Stand-by Power Consumption Product Preview The SCYW99143 is an HV control circuit specifically designed for flyback and other SMPS controllers for applications with extremely low no−load consumption. The internal startup current source supplies the SCYW99143 DIE and slaved SMPS controller during start−up. This function greatly simplifies the design of the auxiliary supply. The built−in Brown−out protection with X2 capacitor discharger allow for omitting inefficient resistor networks which usage would result in unacceptable standby power consumption increase.
