DC DC Converters

DC DC converters are power-electronic circuits used to efficiently convert one DC voltage level to another DC voltage level. They are typically used in a wide range of applications, such as providing power to electronic components, interface circuitry between sensors and logic circuits, and protecting circuits from damaging transients caused by abrupt loads. They are also commonly used as portable power sources in situations when ac power is unavailable.

It is built with a switching capacitor topology that utilizes a pulse-width-modulated inductive topology. The converter offers adjustable output voltage from 1.2 V to 33 V and delivers up to 40 Watts of output power, making it suitable for a wide range of applications.

Application Field

The PTMA403033P2AS DC DC converter can be used in a variety of applications, including embedded systems, telecom equipment, communications, industrial controls, test and measurement equipment, medical devices, and digital consumer products. This converter is also suitable for providing power to LED lighting, motors, robotics, and automotive, among other applications.

Working Principle

The PTMA403033P2AS DC DC converter works by converting a DC input voltage into a regulated, switched-voltage output. In a basic DC DC converter circuit, a bridge rectifier changes the AC voltage into a DC voltage, which is then fed into a step-down converter. This converter reduces the input voltage and ensures a regular, low-voltage output. The converter also uses a pulse-width modulation technique to create high frequency pulses which are mixed with the input voltage in order to further reduce the voltage.

The converter has a wide range of adjustable output voltage from 1.2 V to 33 V, which ensures that the desired voltage can be set for any given application. The output voltage is regulated by comparing the feedback voltage with the reference voltage. The feedback voltage is then used to regulate the output power and ensure that there is no unnecessary power loss. The value of the output voltage is kept within peak voltage variation so that the voltage remains stable even when the load varies.

Furthermore, the PTMA403033P2AS converter also provides a number of protection features for ensuring reliable and safe operation. Its short-circuit protection circuit shuts down the output when the load becomes too low or short circuits, while its over-temperature protection circuit will shut down the output when the internal temperature becomes too high, preventing the converter from damage.

Conclusion

The PTMA403033P2AS DC DC converter is a reliable and efficient two-stage switching power supply that is suitable for a wide range of applications. It offers adjustable output voltage from 1.2 V to 33 V and delivers up to 40 Watts of output power. Its pulse-width modulated inductive technology ensures efficient power conversion, and its short-circuit protection and over-temperature protection guarantees reliable and safe operation.
