Offline switchers and AC/DC converters enable the conversion of alternating current (AC) to direct current (DC) for various applications. Offline switchers integrate switching functionality with AC/DC conversion, making them versatile solutions for power supplies, adapters, and converters. These components are essential in electronics ranging from consumer electronics to industrial equipment, offering efficiency, compactness, and reliability in power delivery. Higher power ratings, advanced features, and superior efficiency typically result in higher prices. When purchasing the switchers and converters, determine the power requirements of your application, including voltage and current ratings, efficiency targets, and any specific features needed such as power factor correction (PFC) or input/output protections. Additionally, consider the form factor and package type that best suits your application, taking into account space constraints and assembly requirements.
