Working Principle of MAX15059BATE+T

The MAX15059BATE+T is based on a traditional buck converter design, but optimized for higher efficiency and superior ripple rejection. It utilizes voltage-mode control, low on-resistance output MOSFETs, an external compensation network, and a precision voltage reference.The chip begins by ramping up the output voltage until it reaches the point of regulation (which is typically 0.75V higher than the target output voltage). The internal MOSFET switch then turns on, reducing the voltage drop across the output MOSFETs to the target output voltage. The output voltage is then maintained at the target voltage and switched at a frequency of the user-defined PWM frequency.To reduce the output voltage ripple, the chip utilizes a power factor correction (PFC) circuit, which helps maintain a constant voltage by adjusting the current waveform to match the voltage waveform. This improves the power factor and total harmonic distortion of the output waveform, allowing it to power sensitive electronic devices without interference.
