Working Principle

The SC1112TSTRT operates as a switch mode voltage regulator, using a combination of pulse width modulation (PWM) and pulse frequency modulation (PFM) to regulate the output voltage. The PWM portion of the voltage regulation is used to maintain the output voltage within a specific pre-defined range, while the PFM portion is used to manage the current load and reduce switching losses.

The PWM portion of the voltage regulationalgorithm is used to maintain the output voltage\'s stability within a specific pre-definedrange. This is accomplished by varying the duty cycle of the output pulse to adjust the pulse width and regulate the output voltage.The PFM portion is used to maintain the current load, and reduce switching losses. It is a mathematical approximation of the current load and fine-tunes the output voltage with respect to the actual current load in order to optimize the power efficiency of the system.

The SC1112TSTRT also contains a built-in feedback network for regulating the output voltage. This enables it to accurately track the reference voltage, and keep the output voltage within the desired range. It also provides a programmable current limit for protecting the system from current overloads, and an overvoltage protection to prevent any damage from excessive output voltages.
