With line-compensated overload power protection, TinySwitch-4 devices dramatically reduce maximum overload variation over the universal input voltage range. It is particularly helpful in applications such as PC standby and CV adapters to limit maximum output power during the overload fault condition. TinySwitch-4 also incorporates 725V MOSFET that easily allows 80% de-rating for high reflected voltage and high bus voltage designs. The BP/M pin permits MOSFET current limit to be adjusted up or down, allowing designers to optimize power delivery and efficiency in a variety of physical implementations. An on-time extension function extends low-line regulation range, enabling hold-up time to be met with lower values of input capacitance. Used in PC standby and other auxiliary supplies, DVD/PVR, other low power set top decoders, supplies for appliances, industrial systems, metering, chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
