Circuit diagram of boost DCDC converter using HS7076

The picture shows a transformer-coupled DCDC converter circuit composed of HS7076. The output transformer storage stage is connected in reverse polarity, and the input voltage is 15-30V. The output voltage is 50V. The output current is 300MA. When the circuit is working normally, when the voltage regulator is turned on, the transformer primary passes current and stores energy. The secondary voltage causes the rectifier diode VD to cut off. At this time, the output capacitor C discharges to the load. When the voltage regulator turns off When, the primary current-free diode of the transformer is cut off.
