PT3408C Working Principle

The PT3408C works on the principle of pulse-width modulation (PWM). This is a technique of rapidly switching a voltage on and off within a very short time frame in order to change its average value. In the case of the PT3408C, the input voltage is converted to a pulse width modulated signal whose average value can be adjusted to match the desired output voltage.

The operating frequency of the PT3408C is adjustable from 20 kHz to 1MHz, with a nominal value of 250kHz. This is done by adjusting the value of the external inductor and the compensation capacitor. The device automatically determines the best operating frequency for the current load conditions. This ensures that the system is always running at the most efficient frequency and minimizing power consumption.

The PT3408C features a programmable output voltage range of 1.2V to 30V with a power factor of 95% at full load. The device supports input voltages from 2.5V to 28V, making it suitable for a wide variety of applications. The device is also equipped with overvoltage, overcurrent, and thermal protection, ensuring that the system is protected at all times.
