TNY289PG DIP-8C AC-DC Controllers & Regulators

Description

Product Details With line-compensated overload power protection, TinySwitch-4 devices dramatically reduce the maximum overload variation over the universal input voltage range. It is particularly helpful in applications such as PC standby and CV adapters to limit the maximum output power during the overload fault condition. TinySwitch-4 also incorporates a 725 V MOSFET that easily allows 80% de-rating for high reflected voltage and high bus voltage designs. The BP/M pin permits the 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 the low-line regulation range, enabling hold-up time to be met with lower values of input capacitance.
