Product Summary

The IMP38HC43ESA is a BiCMOS Current-Mode PWM Controller. The IMP38HC43ESA is fixed frequency, high performance, current-mode PWM controller that is pin compatible with bipolar 384x devices but feature improvements resulting from IMP’s BiCMOS processing and circuit design. The IMP38HC43ESA output driver stage has zero cross-conduction current.
