The device can deliver an output voltage up to 24V and a peak output current of up to 5A, making it suitable for powering a wide range of loads. It is easy to integrate into existing systems, making it an ideal choice for applications such as electric vehicles, test and measurement equipment, and power systems for industrial and commercial buildings.

Working Principle

The TN5D61A-HB11-E operates on a full-bridge topology, which requires four switches (two for each bridge) to be controlled by a Pulse Width Modulation (PWM) signal. The PWM signal is generated by the controller IC, which receives an input voltage and a reference voltage. When the PWM signal is high, the bridge switches turn on, allowing current to flow through the inductor and producing a DC output voltage. When the PWM signal is low, the output voltage is clamped to a reference voltage and the inductor supplies energy to the load. This switching action creates a pulsing DC current, which helps reduce power losses associated with the output ripple and improve the overall efficiency of the device. The device also offers a variety of protection features including over-current, over-voltage, and under-voltage protection as well as over-temperature and transient protection.
