Description
The IMP38HC43ESA is a fixed frequency, high-performance current-mode PWM controller. It is part of the 384x series and features improvements made possible by IMP's BiCMOS processing and circuit design. Some notable improvements include zero cross-conduction/shoot-through current, reduced start-up and operating current, lower current-sense delay, higher frequency operation, full supply voltage swing at the output, and a 1% trimmed voltage reference.
One significant improvement is that the output driver stage of the IMP38HC43ESA has zero cross-conduction current. This means that a proprietary output state-machine monitors each output MOSFET and guarantees by design zero cross-conduction current, setting it apart from other PWM devices in the 384x series.
