Working Principles

The FPF2505 is a buck converter, which means it steps down the input voltage to a lower output voltage. It utilizes pulse width modulation (PWM) to regulate the output voltage. The integrated circuit includes a power MOSFET switch, control circuitry, and protection features.

When the enable pin (EN) is high, the FPF2505 starts operating. The input voltage (VIN) is converted to the desired output voltage (VOUT) using the internal power MOSFET switch. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the switch to maintain a stable output.
