Products Detail

The MIC38C4xA are fixed-frequency, high-performance, current-mode PWM controllers with BiCMOS process. They are pin compatible with UC384x series, featuring ultra-low start-up current (100μA typical), low quiescent operating current (4mA typical), CMOS outputs with rail-to-rail swing, up to 500kHz current-mode operation, trimmed 5V bandgap reference, and UVLO with hysteresis. Available in 8-pin SOIC and MSOP-8 packages.
