The 60 kHz fixed switching frequency with 70 % duty cycle ceiling suits compact transformer designs for 50/60 Hz line-powered converters. ## Parametric deep-dive: supply range, protection, and temperature grade The IC operates from an 11.5 V to 23.5 V Vcc supply, with a 13 V start-up threshold that ensures clean power-on from a bulk capacitor. Built-in fault protection includes cycle-by-cycle current limiting and thermal shutdown with hysteresis — no external sense resistor or OTP thermistor needed for basic protection. ## Active production — sourcing and package availability Available in a 16-SOIC (0.154\", 3.90 mm width) surface-mount package, supplied in tube or tape-and-reel per order quantity.","metaTitle":"VIPER16LD STMicroelectronics Offline Switch 10 W 800V","metaDescription":"VIPER16LD STMicroelectronics VIPer plus offline switch: 10 W, 800V breakdown, 60 kHz, flyback/buck/buck-boost, 16-SOIC.
