Overview
ST’s VIPerPlus series of high-voltage converters combine the innovative avalanche-rugged SuperMESH(TM) power MOSFET with state-of-the-art PWM circuitry. The result is truly innovative AC-DC conversion that is efficient, simpler, quicker and - with component count halved - less expensive.
In addition to benefits such as optimized current-mode control and comprehensive built-in protection circuits, the VIPerPlus family represents the easiest solution to comply with the Blue Angel and Energy Star eco norms, with extremely low total power consumption from the mains when the system is in standby mode.
