The TOP232PN is a switching regulator controller that utilizes a flyback topology to convert the input voltage into a regulated output voltage. It operates by controlling the duty cycle of the internal power MOSFET to regulate the energy transfer from the input to the output. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle accordingly to maintain a stable output.
The TOP232PN is commonly used in various power management applications, including:
