INTERIM ISSUE

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 high-  
current 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 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. The STR83145 and STR84145 differ only in their  
maximum ac current rating (10 A and 12 A, respectively).  
The internal sensitive-gate triac is switched by a temperature-  
compensated constant-current gate driver driven by a 15 kHz pulse  
train to reduce power dissipation. The switch-over voltage is accurately  
set during manufacture for consistent operation. An user-adjustable  
delay is provided to ensure start-up in the full-bridge mode. Once  
established (by an input voltage greater than 149 V rms), an integral  
latch holds the full-bridge mode to preclude false application of the  
doubler mode during brownouts, voltage droops, or missing cycles.  
The requirements of low transient thermal impedance and steady-  
state thermal resistance are satisfied in a molded, 5-lead single in-line  
power package. Similar input-voltage switches, with a switch point of  
159 V rms, are also available.
