DC-DC converters are electrical circuits that convert electrical energy from one form to another. The QRW035A0F1-HZ is a particular DC-DC converter. Specifically, it is an isolated DC to DC converter that features low output voltage ripple, low component fragmentation, and high efficiency.

The QRW035A0F1-HZ converter is designed for applications in motion control, power supply, electric vehicle, and high power LED lighting systems. Its small size makes it suitable for space-constrained application environments. The converter also provides a wide operating temperature range. It is designed to operate at temperatures between -40°C and +85°C.

Regarding its working principle, the QRW035A0F1-HZ utilizes a high-frequency transformer to isolate input and output circuits. It converts the input voltage to a regulated output voltage using an independently regulated pulse width modulation (PWM) technique. When the input voltage rises above the set switching voltage, the power converter will operate in continuous conduction mode (CCM). In CCM, the converter controls the conduction angle of the switching element so as to control the average output current. When the input voltage falls below the set switching voltage, the converter will operate in discontinuous conduction mode (DCM). In DCM, the converter reduces the number of switching pulses to obtain an accurate average output current.

The maximum operating input voltage range of the QRW035A0F1-HZ is 5 V to 36 Vdc, and its maximum output voltage is 3.3 V ± 5 %. The efficiency of the converter starts from 84% over wide range input voltage. The converter can deliver an output current up to 15A in CCM and 9 A in DCM. The maximum output power of the converter is 120W when operating in CCM and 20 W in DCM.

The QRW035A0F1-HZ is a powerful and reliable DC-DC converter. It features high efficiency, low output ripple, low component fragments, and wide operating temperature range. It is designed for various applications in industrial, telecommunications, and automotive systems. Its small size and high output power make it suitable for space-constrained environment. With its reliable performance and reasonable cost, the QRW035A0F1-HZ is a great choice for many applications.
