The MIC38C4xA are fixed-frequency, high
performance, current-mode PWM controllers.
Microchip’s BiCMOS devices are pin compatible with
384x bipolar devices, but feature several
improvements.
Undervoltage lockout circuitry allows the ‘42A and ‘44A
versions to start up at 14.5V and operate down to 9V,
and the ‘43A and ‘45A 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 100 μA typical and operating current has been
reduced to 4.0 mA typical. Decreased output rise and
fall times drive larger MOSFETs, and rail-to-rail output
capability increases efficiency, especially at lower
supply voltages. The MIC38C4xA also features a
trimmed oscillator discharge current and bandgap
reference.
The MIC38C4xA family is available in 8-pin SOIC and
MSOP-8 package options.
For fast rise and fall times and higher output drive, refer
to the MIC38HC4x.
