VIPer53E is a single-ended boost converter controller from ST. It features a breakdown voltage of 620V, a RDS(on) of 1 ohm at 25°C and a typical handling output power of 40W for a 85 to 265Vac voltage mains. VIPer53E also features an automatic burst mode, which allows for very low consumption in standby conditions. VIPer53E is mainly used in AC/DC converters for consumer equipment such as set-top boxes, DVDs and VCRs, but can also be used for stand-by power supplies for servers or in home appliances where a very efficient AC/DC power supply in buck topology is needed.
The VIPer53E integrates a PWM driver, MDmesh MOSFET, a start‑up high‑voltage current source and multiple on‑chip protection circuits. It is supplied in surface‑mount DIP‑8 and PowerSO‑10 packages and supports a Vpp supply range from 9 V to 18 V, extending the flexibility for transformer design.
Designed for consumer equipment such as set‑top boxes, DVD players and VCRs, the device also fits standby power supplies for servers and home appliances. It delivers up to 40 W output power (85‑265 Vac) without a heat‑sink, consumes less than 0.5 W in standby, and provides features like burst‑mode operation, over‑voltage and over‑temperature protection, and an adjustable switching frequency up to 300 kHz.
