Working Principles

The TOP202YAI is a switching regulator controller that utilizes pulse-width modulation (PWM) technique to regulate the output voltage. It operates by rapidly switching the power MOSFET on and off, controlling the duty cycle to maintain a stable output voltage. The integrated oscillator generates a fixed frequency signal, which can be adjusted using external timing components. The feedback loop compares the actual output voltage with the desired value and adjusts the duty cycle accordingly. This control mechanism ensures efficient power conversion.
