Working Principle of the TPS60133PWP

The TPS60133PWP utilizes an internal switch to control the output voltage. The input voltage is connected to the transistors’ gate, and the voltage regulator allows the reference voltage to adjust the transistors’ gate operation. When the transistors are closed, the current flows through the output inductor and the output voltage is regulated. The inductor charges the output capacitor, providing the output voltage and current. The internal switches are controlled by the current sense circuit, that senses the output current and controls the switching frequency. When the output current reaches the threshold, the internal switch is switched off.In order to maximize efficiency, the TPS60133PWP provides an adjustable switching frequency, allowing the system to change the frequency according to the needs.
