The pulse width control circuit of DC‐DC converters utilizing an inrush current controller was designed to ensure proper pumping action and avoid latch‐up during power‐up. The converters with controllable latch‐up protection technique were excellently operated at temperatures above 90°C and heavy load capacitances of Mobile LCD panels.
