Working Principle

The S-1132B16-I6T2U voltage regulator operates on a linear switch-mode concept. In this mode, the error amplifier compares the output voltage of the regulator to the reference voltage and then controls the duty cycle of the switch to attain the desired output voltage.The output voltage is then amplified and compared to the voltage reference. When the output voltage falls below the reference voltage, the error amplifier turns on the MOSFET switch and the output voltage rises towards the reference voltage. When the output voltage reaches the reference voltage, the error amplifier turns off the MOSFET switch and the output voltage falls below the reference voltage. This process is also known as Pulse Width Modulation, or PWM.The S-1132B16-I6T2U includes an integrated power transistor that can be used to drive an external N-channel MOSFET, effectively eliminating the issues associated with poor gate drive capability. This, combined with its wide voltage range, enhanced line-feedback compensation and current-sensing circuit, makes it optimal for low-voltage, high-current applications.
