It supports buck, buck-boost, and flyback topologies with a fixed switching frequency of 60 kHz, and delivers up to 8 W of output power without an external power switch. The device includes control features such as enable and soft start, and provides fault protection including current limiting, over-load, over-voltage, and short-circuit protection. ## 60 kHz switching — transformer sizing and EMI The 60 kHz switching frequency is a design anchor for the power transformer and output filter components — at this frequency a ferrite core with moderate cross-section handles the volt-second product for an 8 W flyback, keeping the transformer physically small. The 80 % maximum duty cycle gives headroom for low-line operation in a buck or flyback configuration, allowing the controller to maintain regulation down to the valley of the rectified AC waveform.","metaTitle":"STMicroelectronics VIPER013BLSTR offline switching regulator","metaDescription":"VIPER013BLSTR offline switching regulator from STMicroelectronics. 800V breakdown, 8W output, 60kHz switching.
