UNITRODE UC1875/6/7/8 UC2875/6/7/8 UC3875/6/7/8 DATA SHEET(1)
The Unitrode UC1875 family of integrated circuits implements control of a bridge power stage by phase-shifting the switching of one half-bridge. This allows constant frequency pulse-width modulation in combination with resonant, zero-voltage switching for high efficiency performance at high frequencies.
These devices are available in various packages including 20-pin DIP, SOIC, PLCC, and hermetically sealed cerdip. They operate over temperature ranges from -55°C to +125°C and feature four 2A Totem Pole Outputs with programmable turn-on delay.
