Intended for power supplies with universal inputs (85 V to 265 V rms), the STR83145 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). This eliminates the possibility of user error with adjustable jumpers or switches. Also, the related switch-mode power stage need operate only over a reduced range of dc input voltages when compared with "wide input" power supplies using a Bridge Rectifier only. The reduction in dc input voltage range permits the use of lower-voltage capacitors and leads to a reduction in power stage stresses and power dissipation.
