PMIC - AC DC Converters, Offline SwitchersThe VIPER15HDTR is an integrated switch mode power supply (SMPS) controller IC designed to support a variety of AC/DC power applications. It is a single-chip solution that reduces the bill of materials (BOM) and development time needed for power supply designs.The VIPER15HDTR offers a host of features that make it an ideal choice for offline applications, including an adjustable PFC/PWM controller, a programmable switching frequency, and a wide range of switching current and output voltage capability. It also combines a high efficiency, low noise design with a small footprint, giving it an advantage over larger AC/DC controllers.The VIPER15HDTR offers several advantages for offline applications, including a wide input voltage range of 85V~265V AC and a start-up time of 8ms. It also offers a wide operating temperature range of -40°C - +125°C, making it suitable for industrial and commercial applications. Additionally, it has a wide array of features, such as over-voltage, under-voltage, and over-temperature protection, making it a safe choice for power applications.The VIPER15HDTR uses pulse width modulation (PWM) technology to convert an AC input voltage into a DC output through a switch mode power supply. When the input voltage is applied, a high-frequency signal is generated which is used to drive the switch. When the switch is turned on, the input voltage is converted into a constant output voltage. When the switch is off, the energy stored in the output capacitor is discharged through a rectifier. This process is repeated, allowing for a continuous output voltage.The PWM technology also allows the VIPER15HDTR to offer a highly efficient power conversion. Thanks to its high switching frequency, which ranges from 4kHz to 500kHz, it can achieve up to 94% efficiency. Additionally, its multi-mode switching technology ensures smooth current transfer, low ripple, and faster transient response.The VIPER15HDTR also features a comprehensive set of protection features. These include over-voltage, under-voltage, and over-temperature protection. It also offers cycle-by-cycle current limiting, which helps protect the user’s circuit from overloads. The VIPER15HDTR’s integrated fault protection greatly reduces the need for external components, minimizing design costs and risks.In summary, the VIPER15HDTR is an ideal choice for offline applications thanks to its wide input voltage range, high efficiency, integrated protection features, and small footprint. Its advanced control and protection features make it a reliable choice for powering electrical equipment in industrial and commercial applications.
