Working Principle of MAX1836EUT33#TG16

The MAX1836EUT33#TG16 is designed with a Pulse Width Modulation (PWM) control architecture. This switching regulator works by cyclically switching the power MOSFET at a fixed frequency. The duty cycle of this ON/OFF switching is regulated to control the regulated output voltage. Therefore, the switching frequency is maintained by the internal oscillator while the duty cycle is accurately regulated by a servo loop to maintain output voltage.The MAX1836EUT33#TG16 employs a low output ripple architecture in order to minimize output noise. This is done by controlling the average inductor current using the voltage feedback from the output. The oscillator also has a special function to ensure smooth ramp times of the gate signals. This prevents peak inductor current or high current transients and reduces power dissipation.The MAX1836EUT33#TG16 also provides protection for under-voltage and over-voltage conditions. It will shut down the output voltage in extreme conditions to protect the system.
