The VIPer53E is an AC/DC converter with a breakdown voltage of 620V, an RDS(on) of 1Ω at 25°C, and a typical output power of 40W for a voltage mains of 85 to 265Vac. It does not require a heat-sink. The total power consumption of the converter is less than 0.5W in stand-by mode, making it compliant with the Blue Angel Eco or Energy Star Program. The VIPer53E is primarily used in AC/DC converters for consumer equipment such as set-top boxes, DVDs, and VCRs. It can also be used for stand-by power supplies for servers or in home appliances where a highly efficient AC/DC power supply in buck topology is needed.
The VIPer53E integrates a PWM driver, MDmesh MOSFET with a 620 V breakdown voltage, a high‑voltage start‑up current source and multiple on‑chip protection circuits. It is offered in surface‑mount DIP‑8 and PowerSO‑10 packages and can operate without a heat‑sink at up to 40 W output power.
Typical applications include AC/DC converters for consumer electronics such as set‑top boxes, DVD players and VCRs, as well as standby power supplies for servers and home appliances. The device supports an external switching frequency up to 300 kHz and offers low standby consumption (<0.5 W).
