IP1212SA

DC-DC converters are electronic circuits that convert direct current from one voltage level to another. The IP1212SA is a single output 3-phase DC-DC converter that provides isolated power for powertrain applications. It is compliant to EN 50155, a European standard that sets the requirements for electronic railway equipment, making it suitable for applications such as traction control systems, generator sets, and more.

The IP1212SA is a synchronous type converter, which means that it can be switched on and off without the need for resistors or capacitors, making it more efficient and reliable. It works by converting a DC input voltage to an intermediate DC bus voltage, then converting this bus voltage to a regulated DC output voltage. This allows the voltage to be tailored to meet the power requirements of the application.

The IP1212SA offers a wide range of operating input and output voltages, allowing it to be used in various applications. It can operate from an input voltage of 7.5 to 48V, and can provide a regulated output voltage between 10.5 and 48V. It is also capable of delivering up to 5kW of power.

The IP1212SA contains two main circuits: the power stage and the control stage. The power stage is made up of a pair of independently isolated, synchronous DC-DC converter ICs, which use a peak current mode control scheme to convert the DC input voltage to a stable intermediate bus voltage. The control stage then regulates the intermediate bus voltage, allowing the user to adjust the output voltage to the required level.

The IP1212SA also offers robust protection features, such as under voltage protection, over temperature protection, and over voltage protection. It also has a built-in current limit circuit, which prevents the output from exceeding the limits set by the user. This makes the IP1212SA suitable for use in applications that require stringent power supply requirements.

Overall, the IP1212SA is a versatile, robust and reliable DC-DC converter suitable for powertrain applications. With its wide input and output voltage range and high power capability, it is an ideal solution for a range of applications.
