DC DC converters have been around since the 1940s when they were originally used in computers and other machines. As technology has developed, DC DC converters are now used in a wide range of applications and are used to operate, regulate and monitor power systems. The PT6901N is a DC DC converter designed specifically for industrial applications.

The PT6901N is a high-performance step-down/step-up DC DC converter with a wide voltage input range of 4.5V to 34V. It is designed for industrial applications and is suitable for use in harsh environments. It has a wide output voltage range of 0.8V to 24V at 5A with excellent efficiency and control performance. It is also capable of working in both a buck-boost or a non-isolated buck-boost configuration.

The PT6901N features a digital power system management (DPSM) system that allows users to control and monitor current, voltage and temperature in real time via an I2C. It also supports parallel operation, making it possible to configure multiple PT6901N DC-DC converters to work in tandem. This makes the PT6901N ideal for industrial and automotive applications where redundant power supply is critical.

The working principle of the PT6901N is based on a pulse width modulated (PWM) control circuit, which is used to regulate the amount of voltage and current supplied to the load. In order to regulate the output voltage, a PWM signal is generated by the DC DC converter, which is then used to switch the transistors on and off at a certain frequency. The frequency of the PWM is controlled by a parameter called the switching frequency, which can range from 10kHz up to 1MHz. The frequency of the PWM signal is proportional to the output voltage, so by changing the switching frequency, the output voltage can be adjusted.

The PT6901N also features a unique step-down/step-up function which allows it to work as a buck converter to step down the voltage, or as a boost converter to increase the output voltage up to 24V. This function is especially useful in applications such as automotive and industrial applications, and it helps to ensure fault-tolerant operation. Additionally, the PT6901N also comes with integrated EMC protection which helps to keep the converter from interfering with other devices in the system.

The PT6901N is a powerful and reliable DC DC converter that is designed to enable higher efficiency and power in industrial and automotive applications. With its wide voltage input range, high current output capabilities, integrated fault protection, and step-down/step-up capabilities, the PT6901N is a great choice for those who need a reliable and efficient DC DC converter.
