DC/DC converters are essential components in a variety of electronic systems. The ATH15T033-9SJ is a versatile full-bridge DC/DC converter with a wide working range and high power density. The converter is specially designed to provide reliable, efficient, high-performance power conversion for battery-powered and/or DC source systems.

The ATH15T033-9SJ is a full bridge DC/DC converter with a primary input voltage of 24Vdc. The maximum output power is 15W at 3.3V output. The conversion efficiency of the ATH15T033-9SJ is up to 95%, making it an ideal solution for energy-saving applications. The unit includes a comprehensive protection package, including an input under voltage protection, output overvoltage protection and output short circuit protection.

The versatile power provided by the ATH15T033-9SJ makes it suitable for a wide range of applications. It can be used for system power supplies, low voltage industrial control, computer systems, telecommunications equipment, vehicle system power supplies and many more. The wide range of voltage input and output make the ATH15T033-9SJ a perfect choice for applications where reliable power is a must.

The working principle of the ATH15T033-9SJ is based on a full bridge topology. The full bridge topology is a single-ended primary inductor converter ( SEPIC ) which use an inductor in combination with two switches to convert single-ended supply voltages to a fixed output voltage. The primary switch ( M1 ) is connected to the input voltage source, while the secondary switch ( M2) is connected to the output voltage. The inductor is placed in series between the two switches.

When M1 is on and M2 is off, the primary inductor is energized, storing energy. When M1 is then switched off, the energy stored in the primary inductor will flow through the secondary switch M2 to the load and the output voltage is held at the desired level. By varying the switch duty cycle, the output voltage can be regulated.

The ATH15T033-9SJ also features an adjustable soft start function, which will limit the maximum current draw in startup. This is essential for applications such as battery-powered systems which require protection against inrush current causing a battery to be discharged too quickly. Additionally, when the load begins to draw more current than the converter can provide, The ATH15T033-9SJ has an adjustable over-current protection and an adjustable short-circuit protection to protect the converter and the load.

In conclusion, the ATH15T033-9SJ is a versatile full bridge DC/DC converter which offers reliable, efficient, high performance power conversion for battery-powered and/or DC sources. It features a wide input voltage range, a wide output voltage range, adjustable soft start, adjustable over-current protection and adjustable short-circuit protection. The converter is an ideal choice for energy-saving applications in a variety of industries.
