BD9S231NUX-CE2

BD9S231NUX-CE2 is a single synchronous buck DC/DC converter for automotive with built-in low on resistance power MOSFETs. It is capable of providing current up to 2A. The small inductor is applicable due to the high switching frequency of 2.2MHz. 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. Application includes automotive equipment, other electronic equipment.
