It is capable of providing up to 1080 watts of steady state output power and features a wide adjustable input voltage range of 10 ~ 260 VDC. The high efficiency design is capable of 94.7% efficiency, and its high power density and compact design make it the ideal choice for applications where space is a concern.

In terms of output, the PT6724C features a wide adjustable output voltage range of single output 2-70V, dual output 5-70V, and triple output 8-70V. It also features a wide load range from 0 - 1080W without the need for de-rating, making it an ideal choice for a variety of applications such as power supplies, telecom systems, IT equipment, consumer electronics, and automotive systems.

Working Principle

The PT6724C DC-DC converter features a switching topology which utilizes MOSFET switches to convert the input voltage to the desired output range. The general working principle of this switching topology is illustrated in the diagram below.

As illustrated, the DC input voltage is first fed through a filtering capacitor in order to remove any high-frequency noise that can affect the performance of the converter. This filtered input voltage is then fed into the MOSFET switches, which are controlled by a Pulse Width Modulator (PWM). The PWM is used to regulate the power being delivered to the load. The MOSFET switches are driven by the PWM, causing them to open and close in an alternating sequence which causes the input power to be switched on and off. The on/off cycle of the MOSFET switches is what causes the input voltage to be converted to the desired output voltage.

The PT6724C DC-DC converter also features a number of safety features to ensure reliable operation, such as input voltage surge protection, overvoltage protection, and short-circuit protection. It also features adjustable power-limit and adjustable output current limit, making it the ideal choice for applications that require robust and reliable power conversion.

In conclusion, the PT6724C is a versatile DC–DC converter designed for heavy-duty current applications. It is capable of providing up to 1080 watts of steady state output power, and features a wide adjustable voltage range of 10 ~ 260 VDC. It features a high efficiency design with 94.7% efficiency, and a wide load range without de-rating. It also features a slew of safety features to ensure reliable operation, making it a great choice for applications that require robust and reliable power conversion.
