DC DC converters are a versatile and wide-ranging technology which are used in a range of different applications, from automotive to aerospace. The PTN78020WAZT is a highly efficient, digitally-controlled multi-stage DC/DC converter, designed to provide up to 150 watts of power in the most compact form factor.

The PTN78020WAZT provides designers with an integrated solution for applications requiring a low-noise, low-power, and high-efficiency DC/DC converter. This unit features a digitally controlled switching mode power supply, with integrated DC/DC conversion and regulation. With low input and output noise, this unit offers efficient conversion from a variety of input sources, ensuring that the user can customize their system to suit their needs.

When it comes to applications, the PTN78020WAZT is ideally suited for use in distributed power architectures and in harsh environments. It can be used in a variety of applications such as avionics, monitoring equipment, machine vision systems and medical imaging.

The PTN78020WAZT features a multistage topology which delivers up to 150W of power with very low output voltage ripple, ensuring that the converter will always operate at peak efficiency. The unit also incorporates a dynamic voltage control loop, allowing for output voltage adjustment over a wide range. This allows the user to optimize the unit for their specific application and requirements.

In terms of working principle, the unit features a pulse width modulated (PWM) controlled, multi-stage topology with two buck converters and a second stage boost converter. The two buck converters are the main element of the system, converting a 12V input to an adjustable output voltage of up to 45V. The low-side buck converter is used to drive the second stage boost converter, which ramps up the voltage for further step-up conversion.

The PTN78020WAZT converters also feature remote on/off control through a logic-level input pin, and thermal protection to prevent damage in case of overheating. This makes the unit ideal for applications where space and power efficiency are key considerations.

In conclusion, the PTN78020WAZT is a versatile and highly efficient digitally-controlled alternative to traditional DC/DC converters. With its incredibly low input and output noise, high power output and multi-stage topology, this unit is well suited for a wide range of applications - from avionics to medical imaging, and more.
