It supports buck, buck-boost, and flyback topologies, making it a flexible building block for low-power AC-DC converters and auxiliary supplies. Rated for 7 W output power, the device operates from a Vcc supply range of 4.5 V to 30 V and delivers a fixed switching frequency of 30 kHz. The internal start-up circuit requires only 8 V to begin switching. On-chip fault protection includes current limiting, over-temperature shutdown, over-voltage protection, and short-circuit protection, reducing the need for external supervisory components. Output isolation is configurable as either isolated or non-isolated, giving the designer freedom to choose the feedback method — optocoupler for isolated flyback or simple resistor divider for non-isolated buck.","metaTitle":"STMicroelectronics VIPER012XSTR offline switching regulator","metaDescription":"VIPER012XSTR from STMicroelectronics: 800 V avalanche-rugged power MOSFET, 7 W output, 30 kHz fixed frequency.
