A source of DC (direct current) can be converted from one voltage to another using a DC-DC Converter IC. These kinds of components are frequently found in portable electronic devices and any other gadgets that rely on batteries for power instead of an external power source. The battery in the gadget provides power at a voltage that may not be adequate for all internal circuits.
Due to individual circuit needs, DC-DC converter ICs make sure that the necessary voltage is given to each circuit. By keeping the input energy for a short period of time and releasing it to the output at a different level, converter ICs can change the voltage inside the system, increasing or decreasing it. In addition to controlling output voltage, DC-DC converter ICs optimise energy harvesting.
The Global DC-DC Converter IC market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
For automotive applications like infotainment and ADAS (Advanced Driver Assistance Systems) including increasingly sophisticated onboard sensors and cameras, ROHM developed the buck DC/DC converter IC with built-in MOSFET (Switching regulator), BD9S402MUF-C.
As technical advances in accident prevention and autonomous driving continue to advance, safety standards in the automotive industry have risen recently. Power supply ICs must perform more steadily even under extreme load current fluctuation conditions as a result of the increasing sophistication of SoCs and MCUs that manage ADAS including onboard sensors and cameras.
Comparing the automotive secondary DC/DC converter ICs with equal performance to the IC that uses QuiCurTM technology, the latter offers the most stable operation in its class.
The new BD9S402MUF-C is a compact secondary power supply solution that supports output voltages as low as 0.6V and 4A output current at switching rates higher than 2MHz. This solution is required by secondary power supply applications for high performance MCUs and SoCs that are becoming more complex.
Additionally, it incorporates patented QuiCur high-speed load response technology, enabling steady operation at an industry-leading 30mV (measured conditions: 5V input voltage, 1.2V output voltage, 44F output capacitance, load current variation 0 to 2A/2s).
This amounts to a 25% decrease in output voltage fluctuation compared to class-leading standard devices with equal functionality, which makes it perfect for use in the newest ADAS with challenging power supply requirements that demand steady operation within 5% even with low voltage output.
