VIPer11 Energy saving off-line 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 480 mA (VIPER114) flyback, buck and buck boost converters is 590 mA (VIPER115) supported. The integrated HV startup, sense- FET, error amplifier and oscillator with jitter allow Wide supply voltage range: 4.5 V to 30 V a complete application to be designed with the Minimized system input power consumption: minimum number of components. Less than 10 mW at 230 V in no-load AC condition Figure 1. Basic application schematic 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) 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 2018 DocID029875 Rev 2 1/35 This is information on a product in full production. www.st.com.
