电流模式PWM控制器 CURRENT-MODE PWM CONTROLLERS
With the current controller from Texas Instruments, you can be assured that the voltage entering a sensitive circuit is modulated correctly. 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. Its switching regulator has a frequency of 500 kHz. 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 97Typ %. This current mode controller has a minimum operating temperature of 0 °C and a maximum of 70 °C.
