Working Principle

The RD3364A uses PWM control technology to achieve high efficiency. In this process, the voltage source is compared with the internal voltage reference and fed back to the PWM signal generator through an error amplifier. The PWM signal will be sent to the gate of the MOSFET to adjust the switching frequency and the output voltage. This loop control is based on the inversion voltage of the input, giving the feedback voltage a reference voltage.

In the process of driver drive, under normal conditions, the PWM signal is sent to the MOSFET gate to control the switching frequency. The output voltage can be adjusted by controlling the conduction duty cycle of the switch. The RD3364A achieves excellent performance, efficiency and reliability by controlling the voltage and current at both ends respectively.
