It delivers up to 8 W in a flyback or buck topology, with the internal 800 V breakdown MOSFET handling universal mains input (85–265 VAC) with margin for line surges. Switching at 30 kHz, the part uses a fixed-frequency architecture that simplifies transformer design compared to higher-frequency parts, though the magnetics will be physically larger. The 70% maximum duty cycle supports moderate step-down ratios in flyback designs. ## Supply and startup voltages that set the bias rail The Vcc supply range spans 11.5 V to 23.5 V, with a 13 V startup threshold. This means the auxiliary winding must deliver at least 13 V to kick the controller on, and the bias rail needs to stay below 23.5 V during steady-state operation — a common range for off-line flyback bias windings. The junction temperature rating of -40°C to 150°C covers industrial and outdoor enclosures, but the 150°C absolute maximum junction temperature means the thermal design must keep the junction below that at full load and high ambient. The 10-SSOP package has a moderate thermal pad; a 4-layer board with thermal vias under the exposed pad is recommended for sustained 8 W output. As an active, non-obsolete part, it is sourced through our distribution network per RFQ.","metaTitle":"VIPER06XSTR ST VIPer™ plus Offline Switcher 8 W 800 V 30","metaDescription":"STMicroelectronics VIPER06XSTR offline switching regulator, 8 W output, 800 V breakdown, 30 kHz switching, 10-SOP package.
