BD9E105FP4-EVK-001

BD9E105FP4-EVK-001 is a evaluation kit for BD9E105FP4-Z 1-ch buck DC/DC converter with integrated FET. This EVK has been developed for synchronous buck DC/DC converter customers evaluating BD9E105FP4-Z that outputs 5V from 12V to 24V input voltage range. The output range is from VIN x 0.1 (more than 0.7V) to VIN x 0.8 and it can be designed as 0.596V x (R2+R3) / R3 by external resistors. The current mode control DC/DC converter provides high-speed transient response performance. Additional protection functions include a built-in soft start function to prevent inrush current at startup, OVP (Over Voltage Protection), UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown Detection), SCP (Short Circuit Protection), and OCP (Over Current Protection). Light load mode operation provides better efficiency in light-load conditions. Typical applications include home appliance, secondary power supply and adapter equipment and communication equipment.
