UC1843B-D - HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER
The UTC UC1842B-D/1843B-D are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter applications with minimal external parts count.
The differences between UC1842B-D and UC1843B-D are the under-voltage lockout thresholds.
