The BD28C54FJ-LBE2 from ROHM Semiconductor is a Pulse Width Modulation (PWM) type DC-DC Converter that is designed for industrial equipment and photovoltaic (PV) inverter applications. It requires an input voltage of 6.9-28 V. This converter uses the PWM current mode method and supports both isolated and non-isolated devices. It includes a VDD UVLO feature with a start-up voltage of 14.5 V and a shutdown voltage of 9 V that supports both Si and SiC of MOSFET. This converter supports the connection of a current detection resistor, which enables accurate monitoring of the output current. It consumes less power and has a switching frequency that can be set by an external resistor and capacitor. This converter benefits from over current protection function per cycle, ensuring safe operation. It is available in a surface-mount package that measures 4.9 x 6.0 x 1.65 mm.
