The growth of data centers, automobiles, and smartphone applications has increased significantly in recent years. With the growing demand, opportunities, rising investment, and increasing annual production, the automobile industry is a growth engine for India’s economy. In the data center applications, 48V DC is generated from the AC grid using a rectifier and is then stepped down to a 12V DC using Intermediate Bus Converter (IBC). Multiphase buck converters are a popular choice to step down this 12V to 0.8-3.3V and supply high dynamic currents to the ASICs, processors, and I/O devices due to the technical benefits they offer. In the case of automotive applications, the entire architecture is similar to that of data centre except that 48V is generated from a battery and is then stepped down to 5V using front-end regulators, which is then stepped down to 0.8V-3.3V using multiphase buck to meet the current requirements of the power-hungry application processor. In the case of smartphones, 3.8V battery voltage is directly stepped down to 0.9V using multiphase buck converter without any intermediate bus converter (IBC)
