The MIC38C4x are fixed frequency, high performance, current-mode PWM controllers. BiCMOS devices are pin compatible with 384x bipolar devices but feature several improvements. Undervoltage lockout circuitry allows the '42 and '44 versions to start up at 14.5V and operate down to 9V, and the '43 and '45 versions start at 8.4V with operation down to 7.6V.

High-performance, low-power BiCMOS Process
Ultra-low start-up current (50μA typical)
Low operating current (4mA typical)
CMOS outputs with rail-to-rail swing
Fast 40ns output rise and 30ns output fall times
-40°C to +85°C temperature range meets UC284x specifications
