UCC25600D, ШИМ контроллер изолированный связь по напряжению 8-SOIC

Описание UCC25600D The UCC25600D is a 8-pin High Performance Resonant Mode Controller designed for DC-to-DC applications using resonant topologies, especially the LLC half-bridge resonant converter. The internal oscillator supports the switching frequencies from 40 to 350kHz. This high-accuracy oscillator realizes the minimum switching frequency limiting with 4% tolerance, allowing the designer to avoid over-design of the power stage and, thus, further reducing overall system cost. The programmable dead time enables zero-voltage switching with minimum magnetizing current. This maximizes system efficiency across a variety of applications. The programmable soft-start timer maximizes design flexibility demanded by the varied requirements of end equipment using a half-bridge topology. By incorporating a 0.4A source and 0.8A sink driving capability, a low cost, reliable gate driver transformer is a real option. • Variable switching frequency control • Programmable minimum switching frequency with 4% accuracy (3% accuracy, -20 to 105°C temperature) • Programmable maximum switching frequency • Programmable dead time for best efficiency • Programmable soft-start time • Easy ON and OFF control • Over-current protection • Over-temperature protection • Bias voltage UVLO and overvoltage protection • Integrated gate driver with 0.4A source and 0.8A sink capability • Green product and no Sb/Br Максимальная рабочая температура+125 °CДлина4.9ммКоличество выходов2ПроизводительTexas InstrumentsТип корпусаSOICМинимальное входное напряжение11,5 ВТип монтажаПоверхностный монтажМинимальная рабочая температура-40 °CШирина3.91ммВысота1.58ммЧисло контактов8Размеры4.9 x 3.91 x 1.58ммМаксимальное входное напряжение18 ВВес, г0.15
