  • Overview
    VIPER37LE Product overview

    Make electricity usable by implementing this VIPER37LE AC to DC converter from STMicroelectronics. This AC to DC power converter supports flyback topology. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This AC to DC power converter has a minimum operating temperature of -40 °C and a maximum of 150 °C.

    VIPER50A-E Product overview

    The VIPER50A-E is a SMPS Primary IC made using VIPower M0 Technology, combines on the same silicon chip a state-of-the-art PWM circuit together with an optimized, high voltage, vertical power MOSFET (700V/1.5A). It is compatible from both primary/secondary regulation loop despite using around 50% less components when compared with a discrete solution. Burst mode operation is an additional feature of this device, offering the ability to operate in stand-by mode without extra components.
