Schaltpläne zur Ansteuerung des ADJ-Eingangs eines ZXLD1366
Driving the ADJ Input via Open Collector Transistor PWM ADJ ZXLD1366 GND This scheme uses the 50k resistor between the ADJ pin and the internal voltage reference as a pull-up resistor for the external transistor. Driving the ADJ Input from a Microcontroller MCU 3.3k ADJ ZXLD1366 GND If the NMOS transistor within the microcontroller has high Gate / Drain capacitance, this arrangement can inject a negative spike into ADJ input of the ZXLD1366 and cause erratic operation, but
