190 LATCHED, UNIVERSAL INPUT-VOLTAGE SWITCHES Intended for power supplies with universal inputs (85 V to 265 V rms), the STR83145 and STR84145 latched, universal input-voltage switches incorporate timing, control, and drive circuitry with a highcurrent triac (bidirectional triode thyristor) switch. Each 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). This eliminates the possibility of user error with adjustable jumpers or
