e: (1) improve the protection. Equipped with soft-start, overcurrent, overheating, over-voltage protection. (2) The maximum output current of 4A, power is 160W, the output voltage between 5.1 ~ 40V adjustable. (3) has a special function: Work prohibition control, synchronous control (go long way in a few slices of output, to ensure consistent operating frequency), the reset circuit (power supply can provide state detection signal), crowbar overvoltage protection circuit (when the output voltage exceeds a preset nominal voltage 20%, generating a drive signal to 100mA, it used to trigger external protection circuit). Figure (c) shows the current unfolding circuit form.
