PTN78020AAS

DC to DC converters are devices that can convert DC power from a higher level to a lower, or from a low voltage to a high, with the greatest efficiency. The PTN78020AAS is one such device, designed for applications in automotive, industrial, communications, consumer, medical and military sectors. It is an isolated, small-sized, high-efficiency and low-cost module, ideal for distributed power supply and battery management.

The PTN78020AAS is a switching, high-frequency DC-DC converter that can operate a wide input voltage range and output power range. It has a wide input voltage range of 4.5 V to 28 V and a wide output voltage range from 0.8 V to 19 V. It comes with a high efficiency of up to 96.5%, negligible are ringing (< 0.5 mV) and excellent EMI performance (EN55032 Class B).

The PTN78020AAS has a working principle based on pulse-width modulation (PWM) technology, in which the input voltage is chopped into pulses of equal frequency, but variable width. The output voltage is then regulated by the width of the pulses generated by the PWM.

The PTN78020AAS can be used in a wide variety of applications. It can be used in automotive applications such as power control units, airbags, engine control and fuel injection. In industrial applications, the PTN78020AAS can be used in HVAC systems, programmable logic controllers, medical devices and other industrial automation equipment. In consumer applications, it can be used in battery management systems, portable electronic devices, wearable electronics and other consumer products.

The PTN78020AAS is ideal for applications that require an isolated DC-DC converter, as it is equipped with 6 kV isolation and transient protection up to 30 kV. It also has active output current limit, short circuit protection and thermal shutdown for maximum system safety.

In summary, the PTN78020AAS is a high-efficiency, low-cost module for distributed power supply and battery management applications in automotive, industrial, communications, consumer, medical and military sectors. It has a wide input voltage range of 4.5 V to 28 V, and can deliver an output power ranging from 0.8 V to 19 V. The PTN78020AAS works on a PWM technology, and provides 6 kV isolation and transient protection up to 30 kV for maximum system safety.
