The 60 kHz fixed switching frequency keeps the transformer small and the EMI predictable — no external frequency-setting resistor needed. The 70 % maximum duty cycle and 11.5 V to 23.5 V supply range suit universal offline inputs (85–265 VAC) with enough headroom for brownout conditions. The 13 V start-up threshold ensures clean power-on sequencing without external start-up resistors. ## Built-in protection reduces BOM count Current limiting and over-temperature protection are integrated — no external sense resistor or thermal shutdown circuit. The output isolation is configurable as either isolated (opto-coupler feedback) or non-isolated, giving the layout engineer one footprint for both designs. The through-hole 7-DIP package (0.300-inch body) allows manual prototyping and rework without hot-air equipment. The base product number VIPER16 covers multiple package and tape options, so the same die is available in surface-mount (SO-8) if a future board shrink requires it.","metaTitle":"VIPER16LN STMicroelectronics Power Management IC – 10 W","metaDescription":"VIPER16LN from STMicroelectronics VIPer™ plus series: 10 W output, 800 V breakdown, 60 kHz fixed switching.
