VIPer01B Energy saving off-line high voltage converter Datasheet - production data Applications Low power SMPS for home appliances, building and home control, small industrial, consumers, lighting, motion control Low power adapters SSOP10 Description Features The device is a high voltage converter smartly integrating an 800 V avalanche-rugged power 800 V avalanche-rugged power MOSFET MOSFET with PWM current mode control. The allowing ultra wide V input range to be AC power MOSFET with 800 V breakdown voltage covered allows the extended input voltage range to be Embedded HV startup and sense-FET applied, as well as the size of the DRAIN snubber Current mode PWM controller circuit to be reduced. This IC meets the most stringent energy-saving standards as it has very Drain current limit protection (OCP) low consumption and operates in pulse frequency Wide supply voltage range: 4.5 V to 30 V modulation under light load. The design of Self-supply option allows the auxiliary winding flyback, buck and buck boost converters is or bias components to be removed supported. The integrated HV startup, sense- FET, error amplifier and oscillator with jitter allow Minimized system input power consumption: a complete application to be designed with the Less than 10 mW at 230 V in no-load AC minimum number of components. condition Less than 400 mW at 230 V with 250 AC Figure 1. Basic application schematic mW load Jittered switching frequency reduces the EMI filter cost: 60 kHz 7% (type L) 120 kHz 7% (type H) Embedded E/A with 1.2 V reference Protections with automatic restart: overload/short-circuit (OLP), line or output OVP, V clamp CC Pulse-skip protection to prevent flux-runaway Embedded thermal shutdown Built-in soft-start for improved system reliability April 2018 DocID031727 Rev 1 1/37 This is information on a product in full production. www.st.comContents VIPer01B Contents 1 Pin setting . 6 2 Electrical and thermal ratings . 7 Electrical characteristics . 9 3 Typical electrical characteristics 13 4 General description . 17 4.1 Block diagram 17 4.2 Typical power capability 17 4.3 Primary MOSFET . 18 4.4 High voltage startup . 18 4.5 Soft-start 20 4.6 Oscillator . 20 4.7 Pulse-skipping . 21 4.8 Direct feedback 22 4.9 Secondary feedback . 23 4.10 Pulse frequency modulation . 23 4.11 Overload protection . 23 4.12 VCC clamp protection . 24 4.13 Disable function 25 4.14 Thermal shutdown 27 5 Application information . 28 5.1 Typical schematics 28 5.2 Energy saving performance . 31 5.3 Layout guidelines and design recommendations . 32 6 Package information 34 6.1 SSOP10 package information . 34 2/37 DocID031727 Rev 1
