Working Principle:

PT78NR112V is a switching regulator based DC/DC converter. The device works on a simple principle of boosting the input voltage to the desired level, stepping down the voltage, and regulating the voltage to maintain its specified output level. The idea behind this is to reduce energy losses and efficiently convert the input voltage to the required level. The device achieves this using semiconductor switches such as MOSFETs and UJTs, and other passive components such as inductors and capacitors.

When the input voltage is applied, the MOSFETs present in the DC/DC converter turn on and off at a rapid rate to convert the voltages. The rate at which the MOSFETs switch is dependent on the feedback given by the voltage regulator. This feedback is then used to drive the MOSFETs so as to maintain a constant output voltage as desired by the circuit.

Apart from the above-mentioned components, the device also utilizes a PWM controller to regulate the switching speed of the MOSFETs. This, in turn, helps in achieving the required output voltage and maintains it over a varying load as well as varying input voltage. The device also utilizes current sense technique during operation which ensures efficient operation and minimal losses. This approach also helps in improving the accuracy of the output voltage and current.

Conclusion:

PT78NR112V is a DC/DC converter which offers a best-in-class price/performance combination suitable for embedded applications. This device is suitable for a wide range of applications in industries such as automotive, industrial, telecom and medical. The device utilizes high-performance components such as MOSFETs and UJT’s to efficiently convert the input voltage to the desired level along with current sense technique for improved accuracy.
