QuiCur™, Nano Pulse Control™, 2.7V to 5.5V Input, 3A Single Synchronous Buck DC/DC Converter for Automotive
BD9S303MUF-C is a synchronous buck DC/DC Converter with built-in low on-resistance power MOSFETs. It can provide current up to 3A. Small inductor is applicable due to high switching frequency of 2.2MHz. It is a current mode control and features fast transient response. The Light Load Mode control improves efficiency in light-load conditions. It is ideal for reducing standby power consumption of equipment. It has a built-in phase compensation circuit. Applications can be created with a few external components.

- PMIC solution for ADAS SoC Reference Design
The intelligent front camera(IFC) integrates a 2 million pixels high-definition camera and supports access to multiple millimeter wave radars, which can implement L2 level forward ADAS function. This solution uses the Horizon Journey2 chip with 4TOPS AI computing power and the Infineon TRAVEO II series CYT4BF microcontroller. By deploying corresponding visual algorithms on Horizon Journey2 to identify obstacles, lane lines, and other traffic elements, and using the Infineon TRAVEO II series CYT4BF microcontroller for vehicle sensor fusion and vehicle control, this solution can achieve ADAS functions such as AEB, ACC, LCC, and TJA. By selecting Rohm PMIC chips with ASIL D functional safety level, such as BD96801Q09 and BD9S303MUF, the reliability and stability of the intelligent front camera(IFC) can be ensured.
