VIPer11 Energy saving offline high voltage converter Datasheet - production data Applications Low power SMPS for home appliances, home automation, industrial, consumer, lighting Low power adapters SSOP10 Description The device is a high voltage converter smartly Features integrating an 800 V avalanche-rugged power MOSFET with PWM current mode control. The 800 V avalanche-rugged power MOSFET power MOSFET with 800 V breakdown voltage allowing ultra wide VAC input range to be allows the extended input voltage range to be covered applied, as well as the size of the DRAIN snubber Embedded HV startup and sense-FET circuit to be reduced. This IC meets the most stringent energy-saving standards as it has very Current mode PWM controller low consumption and operates in pulse frequency Drain current limit protection modulation under light load. The design of 370 mA (VIPER113) flyback, buck and buck boost converters is 480 mA (VIPER114) supported. The integrated HV startup, sense- 590 mA (VIPER115) FET, error amplifier and oscillator with jitter allow a complete application to be designed with the Wide supply voltage range: 4.5 V to 30 V minimum number of components. Minimized system input power consumption: Less than 10 mW at 230 V in no-load Figure 1. Basic application schematic AC condition Less than 400 mW at 230 V with 250 AC mW load Jittered switching frequency reduces the EMI filter cost: 30 kHz 7% (type X) 60 kHz 7% (type L) 120kHz 7%(type H) Embedded E/A with 1.2 V reference Protections with automatic restart: overload/short-circuit (OLP), line or output OVP, max. duty cycle counter, VCC clamp Pulse-skip protection to prevent flux- runaway Embedded thermal shutdown Built-in soft-start for improved system reliability April 2020 DS11873 Rev 5 1/37 This is information on a product in full production. www.st.com.
