- Evaluation Board - BD9S209NUX-TSB-001
This Evaluation Board was developed for ROHM's single Synchronous buck DC/DC converter BD9S209NUX-C. It is a synchronous buck DC/DC converter with built-in low On Resistance power MOSFETs. BD9S209NUX-C accepts a power supply input range of 2.7 V to 5.5 V and generates a maximum output current of 2 A. Small inductor is applicable due to high switching frequency of 2.2 MHz. It is a current mode control DC/DC Converter and features high-speed transient response. It has a built-in phase compensation circuit. Applications can be created with a few external components.
