电流模式PWM控制器 CURRENT MODE PWM CONTROLLER
This current controller by Texas Instruments will generate a proper current for an external system. This current mode controller supports boost|buck|flyback|forward topology. Its single PWM output produces a current of 1000Max mA. 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 has an operating temperature range of 0 °C to 70 °C. This current mode controller"s maximum duty cycle is 100 %.
