电流模式PWM控制器 CURRENT-MODE PWM CONTROLLERS
By controlling the level of voltage through pulse-width modulation, Texas Instruments" controller is the tool for your sensitive external circuit. 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. This part offers a switching frequency of 500 kHz in order to work properly. In order to ensure parts aren"t damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This device has a maximum of 30 V. This current mode controller"s maximum duty cycle is 48Typ %. This current mode controller has an operating temperature range of -40 °C to 85 °C.
