Working Principle

The MAX17242ETPA+T works by boosting the input voltage to a higher level. An integrated switch mode controller, driven by a resonant oscillator, controls an external N-channel MOSFET switch. The integrated controller monitors the output voltage, compensates for variations in the input voltage, and optimizes efficiency to ensure a robust output voltage regulation. The controller also provides seamless transition between 100% PWM duty cycle and Burst Mode operation. The PWM duty cycle is regulated to maintain a desired output voltage in a wide input voltage range.

The device also features an external current mode control loop to establish accurate output current regulation. This loop reduces the peak inductor current, improves system efficiency, and reduces output voltage ripple. Additionally, the MAX17242ETPA+T has integrated current and temperature sensors that ensure precise and robust current and temperature limits. The device also has an active voltage positioner that allows precise control of the output voltage.
