1 / 36 page  March 2016 DocID028751 Rev 1 1/36 This is information on a product in full production. www.st.com VIPer01 Energy saving off-line high voltage converter Datasheet - production data Figure 1: Basic application schematic Features 800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to be covered Embedded HV startup and sense-FET Current mode PWM controller Drain current limit protection (OCP) Wide supply voltage range: 4.5 V to 30 V Self-supply option allows the auxiliary winding or bias components to be removed Minimized system input power consumption: Less than 10 mW @ 230 VAC in no-load condition Less than 400 mW @ 230 VAC with 250 mW load Jittered switching frequency reduces the EMI filter cost: 30 kHz ± 7% (type X) 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, max. duty cycle counter, VCC clamp Pulse-skip protection to prevent flux-runaway Embedded thermal shutdown Built-in soft-start for improved system reliability Applications Low power SMPS for home appliances, building and home control, small industrial, consumers, lighting, motion control Low power adapters Description The device 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, sense- FET, error amplifier and oscillator with jitter allow a complete application to be designed with the minimum number of components. |
