Description
The IMP38C42EPA is a fixed frequency, high-performance current-mode PWM controller. It is pin compatible with bipolar 384x devices but offers improvements due to 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 of the key features of the IMP38C42EPA is its output driver stage, which has zero cross-conduction current. A proprietary output state-machine monitors each output MOSFET, ensuring zero cross-conduction current. This is a unique feature in the PWM device industry.
