PinoutSW2604 Pinout

A current mode PWM (Pulse Width Modulation) switching power supply controller is an integrated circuit (IC) that is used in power supply designs to regulate the output voltage by controlling the switching of power transistors. It operates in a current mode control scheme, where the current flowing through the power inductor is sensed and used as feedback for controlling the power supply output.

The current mode PWM controller monitors the current waveform and adjusts the duty cycle of the switching transistors to maintain a stable output voltage. It compares the sensed current with a reference value and generates a control signal that adjusts the on-time and off-time of the power transistors accordingly.
