DC DC Converters

DC-DC converters are electronic devices or circuits that convert a source of direct current (DC) into a different DC voltage level. It is an essential component of virtually all electronic devices and is used to regulate the power supply of a device. The DC DC converter is used in a wide range of applications, from medical equipment and automotive electronics to consumer electronics, communications, and power tools.The PSB123-7IR is a type of DC DC converter. It is a compact and reliable high conversion efficiency DC DC step down converter module that is designed for electronic platforms such as embedded systems, industrial automation, and automotive applications. The PSB123-7IR consists of two main components: an integrated buck converter IC and an integrated magnetic induction unit. The buck converter IC is an integrated circuit that contains all the necessary components for the power conversion, including a buck regulator, power switches, inductors, and energy storage capacitors. The integrated magnetic induction unit usually consists of two components; a large outer coil and a smaller inner conductor. The outer coil stores and delivers the energy, and the inner conductor acts as the energy return path. The inductor stores energy when the buck converter is on and releases it when the converter is off. This creates an alternating current (AC) waveform that is converted into a DC output voltage. The PSB123-7IR is capable of delivering up to 15W of power with adjustable output voltage from 1.6V to 12V. The output voltage is fully adjustable and can be set to meet the application’s specific requirements. The efficiency of the converter is typically 85%. The converter also has a wide operating temperature range from -40°C to 85°C and a high power density of up to 11W/cm3. The PSB123-7IR is designed with overcurrent, short-circuit, overvoltage, over-temperature protection measures, as well as a power good signal (PG) and soft start function. This helps to ensure a stable output voltage.The PSB123-7IR is commonly used in a wide range of electronic platforms, including embedded systems, industrial automation, and automotive applications. It can be used to regulate the power supply of a device and can provide an adjustable output voltage that meets the specific requirements of the application. The PSB123-7IR\'s high efficiency, high power density, wide operating temperature range, and stability make it an ideal choice for many different applications.
