What is a Power supply IC?

A power supply IC (Integrated Circuit) is an integrated circuit designed for power management and supply. These ICs are responsible for functions such as voltage conversion, overvoltage and overcurrent protection, battery management, and power efficiency optimization. Common types include DC-DC converters, LDO (Low Dropout Regulator), battery charging ICs, and voltage regulators. Power supply ICs ensure efficient energy management and maintain system stability in a wide range of electronic devices.

Application of Power supply IC

１．DC-DC Converter - An IC that converts an input DC voltage to another DC voltage. For example, it can be used to convert a 12V input to 5V or 3.3V, ensuring stable power delivery to devices that require different voltages.
２．LDO (Low Dropout Regulator) - A voltage regulator that works efficiently when the difference between the input and output voltages is small. For example, it is used to convert a 5V source to 3.3V.
３．Battery Charging IC - An IC designed to efficiently charge batteries, such as lithium-ion batteries. It prevents overcharging and overdischarging, which helps prolong the battery's lifespan.
