7 V to 5.
5 V Input, 1 A Single Synchronous Buck DC/DC Converter for Automotive BD9S11xNUX-C series General Description BD9S11xNUX-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 compensation circuit.
Applications can be created with a few external components.
