- Evaluation Board - BD9S231NUX-TSB-001
This Evaluation Board was developed for ROHM’s single Synchronous buck DC/DC converter BD9S231NUX-C. BD9S231NUX-C is a synchronous buck DC/DC converter with built-in low On Resistance power MOSFETs. BD9S231NUX-C accepts a power supply input range of 2.7V to 5.5V and generates a maximum output current of 2A. BD9S231NUX-C generates an output voltage range of 0.8V to VIN using external resistors. BD9S231NUX-C is a current mode control DC/DC Converter and features high-speed transient response.
