DC-DC converters are electronic circuits which convert a given DC voltage level to another DC voltage level. The main application of DC-DC converters is for the purpose of voltage transformation. PTMA403033P1AD is a DC-DC converter, which has two main application fields, isolated and non-isolated DC-DC converter.

Application Fields

In the isolated application field, PTMA403033P1AD provides galvanic isolation between the input and output by means of a transformers, optical and capacitive isolation. It has a wide input voltage range of 4.5V to 14V and can provide one single output of 24V in 0.5A to 3A range. It also has a low output ripple of 40mV (50mA - 3A range).

Additionally, in the non-isolated application field,PTMA403033P1AD has a wide input voltage range with an adjustable output voltage from 2.5V up to 24V, depending on the model and output current. It has very low noise levels and excellent set-up times.

Working Principle

PTMA403033P1AD is a switch mode regulator which operates on a unique switching technique. By pulsing the output voltage at a very high frequency, it ensures that the output current remains low thus providing a very efficient and highly reliable regulator. It also has over temperature protection built into it, to ensure that the IC does not get wrecked in case of any over temperature situation.

To guarantee the output voltage is stabilized even though the input voltage is varying, PTMA403033P1AD is utilizing a DC-DC switching converter which works on the principle of pulse width modulation (PWM). By adjusting the duty cycle of the PWM pulse, the output voltage will remain steady regardless of the input voltage variations.

PTMA403033P1AD combines several technologies in a single IC package providing excellent performance and high reliability. This IC can be used in a variety of application fields, such as in industrial, consumer electronics, automotive, and communication applications.
