BD9A201FP4-EVK-001

BD9A201FP4-EVK-001 is a buck converter with integrated FET. This EVK has been developed for ROHM’s synchronous buck DC/DC converter customers evaluating BD9A201FP4-LBZ and outputs 1.8V from 5V input voltage. It accepts a power supply input range of 2.7V to 5.5V and generates output voltage ranging from 0.8V to 0.7 x VIN using external resistors. The operating frequency is fixed at 1000KHz. 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 rush current at startup, OVP (over voltage protection), UVLO (under voltage lockout), TSD (thermal shutdown detection), SCP (short circuit protection) and OCP (over current protection). It is used in applications such as industrial equipment, products for industrial equipment such as NC machine tools, secondary power supply and adapter equipment, and communication infrastructure equipment.
