BD9S111NUX-C Datasheet | ROHM

2.7 V to 5.5 V Input, 1 A Single Synchronous Buck DC/DC Converter for Automotive BD9S11x NUX-C series General Description BD9S11x NUX-C series is a synchronous buck DC/DC Converter with built-in low On Resistance power MOSFETs. It is capable of providing current up to 1 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 an integrated feedback resistor that sets the output voltage to 1.2 V/1.8 V and a built-in phase pensation circuit. Applications can be created with a few external ponents.
