Bi
CMOS 1A Current-Mode PWM Controllers Final Information
General Description
The MIC38HC4x family are fixed frequency current-mode PWM controllers with 1A drive current capability.
Micrel’s Bi
CMOS devices are pin-compatible with 384x bipolar devices.
Their high output drive, with fast rise and fall times, combined with low startup current make it an ideal PWM controller where high efficiency is required.
Under
voltage 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.
