电流模式PWM控制器 CURRENT-MODE PWM CONTROLLERS
Look no further! The PWM controller from Texas Instruments is the ideal tool for interfacing two different voltage circuits together. With an output that has a voltage of 0 to 30 V, this is power management at its best. Its single PWM output produces a current of 200Max mA. This current mode controller supports boost|flyback|forward topology. You can operate this at a switching frequency of 500 kHz. In order to ensure safe delivery and enable quick mounting of this component after delivery, it will be encased in tape and reel packaging during shipment. This current mode controller"s maximum duty cycle is 97Typ %. This device has a maximum of 30 V. This current mode controller has an operating temperature range of 0 °C to 70 °C.
