Working Principle

HPA02232ARGER use the Buck or Step-Down Conversion topology. This topology works by utilizing an inductor that stores energy and conducts it to the load during the ‘on’ time of the switching FET. Voltage regulation is done via Pulse Width Modulation (PWM). When the current output is set, the PWM circuit will adjust PWM period duration so that the voltage is regulated. The output voltage is compared to the reference voltage and the switching frequency is set using an internal reference oscillator.

The HPA02232ARGER devices also incorporate an enable input for enabling or disabling the output of the regulator and an external synchronous control input for synchronizing the frequency to another component. The output of the regulator is protected by active current limit, short circuit protection, and over-temperature protection.
