There is no frequency foldback or spread-spectrum; the design must accommodate the fundamental and its harmonics in the conducted emissions band. The 80 % maximum duty cycle supports a wide input-to-output voltage ratio in buck-boost and flyback configurations, useful for universal AC input (85–265 VAC) designs where the bulk capacitor voltage can swing from 120 V to 375 V. ## Junction temperature headroom for hot enclosures The 150 °C Tj(max) rating means the thermal shutdown threshold is above the operating limit, so the part can ride through transient overloads without immediate shutdown. ## Integrated protection set reduces BOM count On-chip fault protection covers current limiting, over-temperature, over-voltage, and short-circuit. The output isolation is configurable as either isolated or non-isolated, so the same part can serve a flyback with an optocoupler or a simple buck converter.","metaTitle":"VIPER013LSTR STMicroelectronics offline converter, 7 W","metaDescription":"STMicroelectronics VIPER013LSTR offline switching regulator, 7 W output, 800 V breakdown, 60 kHz fixed frequency.
