Working Principle

The evaluation board of MAX17530AUBEVKIT# utilizes the MOSFET configuration as its switching element, which is enabled by the internal PWM generator and the low-side MOSFET. When the internal PWM generator is enabled, it starts to switch on the high-side MOSFET and the low-side MOSFET alternately, thus forming a switched-mode power supply. The internal PWM generator can be continuously adjusted in frequency and duty cycle to control the output voltage and current.

The position of the voltage divider\'s feedback network is adjusted to the desired output voltage, the load changes and the current sensing is also integrated on the MAX17530AUBEVKIT# evaluation board. The current sensing of the board monitors and provides the current feedback to the PWM generator, so as to achieve an optimal switching speed on the MOSFETs. The result is a high-efficiency, robust switching regulator solution.
