Working Principle
At the heart of the PT8A3245WEX is a voltage regulator circuit. This circuit accepts input from the power source and creates regulated output voltages using switching technology. In most cases, the IC uses pulse-width modulation (PWM) to control the output voltage of the voltage regulator circuit.
The pulse-width modulation is adjusted by the user with the frequency and duty cycle settings. The frequency can be set to any frequency between 4 kHz and 76 MHz, while the duty cycle can be set to any value between 10% and 100%, allowing for precise adjustment of the output voltage. This in turn allows the user to adjust the amount of power supplied to the connected components.
PT8A3245WEX’s dual driver circuit is also used to enhance its power output. The dual driver circuit increases the output power of the voltage regulator by combining the outputs of two separate channels. By combining the outputs, the IC can deliver up to twice the power of a single channel, allowing for greater flexibility and efficiency of power delivery.
