DC-DC Converters have become a very important technology used in a variety of applications. The TRN 3-1222 is a high performance DC-DC Converter, suitable for automotive, industrial, and other applications. It is designed to comply with the latest regulations for automotive applications, and provides a wide range of features and benefits to the customer.

The primary features of the TRN 3-1222 include its auto-oscillating PWM control, same-sense ORing MOSFETs, and its built-in protection against line-feeding, overload, open circuits, and short circuits. It also provides soft start, over-temperature protection, and over-speed protection. Additionally, it has an integrated EMI filter stage that integrates a low-impedance, low-profile, high-frequency 50 ohms shielded filter stage.

The TRN 3-1222 also includes two identical ORing MOSFETs, one for load current sharing, and one for reset current sharing. The MOSFETs are designed to deliver maximum current across a wide, uninterrupted range of temperatures. They also feature protection against over-voltage, over-current, and short circuit conditions. The circuit also provides a built-in reverse current limiter. The MOSFETs are integrated into the circuit in such a way that a low input voltage and low-current transient is maintained, even under high load. Additionally, the circuit features a built-in sequence control function, which controls the reset current sharing and load current sharing when multiple converters are connected together.

The working principle of the TRN 3-1222 is based on two independent and synchronized voltage converters. The first converter produces a steady 5 V output from a range of inputs up to 24 VDC. The second converter is responsible for producing a wide range of outputs from 5 to 24 VDC, depending on the input voltage. The converter acts like an AC voltage transformer, transforming the input voltage into the desired output voltage. In addition, the TRN 3-1222 provides a selectable PWM modulation type. The PWM modulation modulates the output voltage in the form of a sinusoidal waveform. As a result, the output voltage is kept close to its desired value, even when the input voltage is subject to a wide range of fluctuations.

The TRN 3-1222 is a very flexible and reliable solution for automotive, industrial, and other applications. The wide range of features make it suitable for a variety of applications, and its wide input voltage and low-current transient make it very reliable in operation. The added protection against line-feed, overload, open circuit, and short circuit conditions, provide an additional level of safety. Additionally, the built-in EMI filter stage, and the integrated ORing MOSFETs, make it ideal for applications where high current needs to be shared between multiple converters. The TRN 3-1222 is a very reliable and cost-effective solution for a wide range of applications.
