The BD7F100HFN-EVK-001 evaluation board is a product of Rohm Semiconductor\'s Design Solutions division. It is a part of the Bengala power supply family, which was designed to provide designers with an extensive range of efficient and reliable power supplies.

The BD7F100HFN-EVK-001 is classified as an evaluation board for DC/DC & AC/DC(Off-Line) SMPS. This evaluation board is designed to allow users to evaluate the high efficiency power supply BD7F100HFN. The board simplifies the design process and makes the evaluation of the device as straightforward as possible.

The BD7F100HFN-EVK-001 board uses a 5V input voltage and power efficiency up to 98 percent, implemented by a two-line low-side synchronous buck converter. It also offers a number of protection features, including an over voltage protection (OVP), an over temperature protection (OTP) and an over current protection (OCP) for better safety. In addition, the emitter transistor is protected against reverse voltages, which reduces system failure caused by improperly connected external components.

The BD7F100HFN-EVK-001 board’s main features lie in its operating principle. It requires two low voltage sources, namely a DC input voltage (5V) and a variable PWM signal. The input voltage is applied to the circuit, while the PWM signal is used to control the output voltage. The duty cycle of the PWM signal is varied to adjust the output voltage. As the duty cycle increases, the output voltage increases. The circuit can operate in discontinuous or continuous conduction mode, depending on the PWM signal’s frequency. In discontinuous conduction mode, the switching elements never turn off and the average output voltage is equal to the desired output voltage. In continuous conduction mode, the switching elements turn off at the end of every switching cycle and the average output voltage is usually lower than the desired output voltage.

The BD7F100HFN-EVK-001 is an efficient, reliable and feature-rich power supply evaluation board. It offers a comprehensive solution to designers, simplifying the design, development and evaluation process. The board provides a number of protection features for safety and can operate in the discontinuous and continuous conduction modes. The BD7F100HFN-EVK-001 board’s power efficiency and operating principle make it an excellent choice for a wide variety of applications.
