Overview
MIC38C42/3/4/5 Micrel, Inc.
MIC38C42/3/4/5 BiCMOS Current-Mode PWM Controllers General Description The MIC38C4x are fixed frequency, high performance, current-mode PWM controllers.
Micrel’s 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.
All versions operate up to 20V.
When compared to bipolar 384x devices operating from a 15V supply, start-up current has been reduced to 50µA typical and operating current has been reduced to 4.
0 mA typical.
Decreased output rise and f...
