- Evaluation Board - BD9S200MUF-TSB-001
This Evaluation Board was developed for ROHM's single Synchronous buck DC/DC converter BD9S200MUF-C. It is a synchronous buck DC/DC converter with built-in low On Resistance power MOSFETs. The BD9S200MUF-C accepts a power supply input range of 2.7V to 5.5V and generates a maximum output current of 2A. The SLLMTM control provides excellent efficiency characteristics in light-load conditions which make the product ideal for reducing standby power consumption of equipment. BD9S200MUF-C is a current mode control DC/DC Converter and features high-speed transient response.
