Typical Application for Str81145A Latched, Universal Input-Voltage Switches

Beschreibung

• Typical Application for Str81145A Latched, Universal Input-Voltage Switches. Intended for power supplies with universal inputs (85 V to 265 V rms), the STR83145 latched, universal input-voltage switch incorporates timing, control, and drive circuitry with a high-current triac (bidirectional triode thyristor) switch. The device senses the applied ac line potential and automatically switches the rectifier and associated capacitors between a voltage-doubler configuration (for line voltages to 141 V) and a full-bridge configuration (for line voltages greater than 149 V)
