Working Principle of ST1S32PUR

The ST1S32PUR is a high performance DC-DC switching regulator that utilizes Pulse Width Modulation (PWM) to regulate the output voltage. In PWM mode, the output voltage is controlled by varying the duty cycle of the pulses sent to the external MOSFET switch. The PWM duty cycle is generated using a pulse generator and an adjustable error amplifier. The output voltage is then regulated by adjusting the duty cycle of the PWM signal. The PWM duty cycle is also adjustable to provide soft start control.

In linear mode, the output voltage is regulated using a linear regulator. The output voltage is calculated based on the feedback voltage from an external voltage divider. A linear regulator is used to compare the output voltage to an internally programmed regulation voltage and when a difference is detected, the output is adjusted to maintain the programmed regulation voltage.

In addition to the adjustable voltage regulation, the ST1S32PUR also has two programmable protection circuits that can be used to prevent wrong connections and possible malfunctions in the system. These protection circuits are adjustable by selecting the fault levels and hysteresis voltage levels.
