Enroll to Review the Rohm Buck Converter Eval Kit BD9G500EFJ-EVK-001

Table of contents


BD9G500EFJ-EVK-001 uses BD9G500EFJ-LA (Single Buck DC/DC Converter) to output 5V from a 48V input voltage. The input voltage of theBD9G500EFJ-LA is from 7V to 76V and the output voltage is configurable from 1V to 0.97 x VIN V with external resistors. The operating frequency is configurable between 100 kHz and 650 kHz with an external resistor connected to RT pin. This is a current mode control DC/DC converter that provides fast transient response performance and simple phase compensation setup. Built-in functions include variable soft start function which prevents inrush current at startup, UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown Detection), OVP (Over Voltage Protection), OCP (Over Current Protection) and OVDIS (Over Voltage Discharge).
