VIPer11 Energy Saving Off-Line High Voltage Converter

STMicroelectronics' VIPer11 high voltage converter for ultra-low consumption and compact SMPS

STMicroelectronics' VIPer11 Energy Saving Off-Line High Voltage Converter STMicroelectronics' VIPer11 is a high voltage converter smartly integrating an 800 V avalanche-rugged power MOSFET with PWM current mode control. The power MOSFET with 800 V breakdown voltage allows the extended input voltage range to be applied, as well as the size of the DRAIN snubber circuit to be reduced. This IC meets the most stringent energy-saving standards as it has very low consumption and operates in pulse frequency modulation under light load. The design of flyback, buck, and buck-boost converters is supported. The integrated HV startup, senseFET, error amplifier and oscillator with jitter allow a complete application to be designed with the minimum number of components.

Features
High efficiency to comply with the most stringent energy saving regulations It automatically switches to pulse frequency modulation when the load is light and allows standby power consumption below 10 mW High reliability for an improved SMPS lifetime 800 V avalanche-rugged power MOSFET allows ultra-wide V_AC input range to be covered Pulse-skip protection Disable pin to set the input or output OVP High versatility fitting the most popular topologies and wide voltage ranges It can be used in flyback, buck, and buck-boost converter topologies Accepts wide supply voltage range from 4.5 V_CC to 30 V_CC		High integration for the minimum number of external components Fixed frequency with jittering reduces the EMI and allows small filters Self-supply option allows auxiliary winding or bias components to be removed Integrated high-voltage start-up, senseFET, error amplifier SMPS with a 5 V output voltage in applications up to 7 W, such as White goods, cooking Small home appliances Home lighting, auxiliary supplies, LED lighting Home automation
