STMicroelectronics VIPER™ VIPER53SP is a high-performance offline flyback controller designed for AC/DC conversion applications. This device integrates a high-voltage power MOSFET, operating up to 300kHz, enabling compact and efficient power supply designs. Key features include internal soft-start, advanced frequency control, and robust fault protection mechanisms such as over-current, over-load, over-temperature, and short-circuit protection. The VIPER53SP utilizes a flyback topology with isolated output, suitable for power levels up to 65W. It operates from a Vcc range of 8.4V to 19V, with a start-up voltage of 11.5V and a breakdown voltage of 620V. The component is housed in a 10-PowerSO package with an exposed bottom pad for enhanced thermal management and is supplied in tubes. Its capabilities make it a preferred choice for consumer electronics, industrial automation, and lighting applications.
