电流模式PWM控制器 CURRENT-MODE PWM CONTROLLERS
Properly supply the right amount of current to an external system using this current controller from Texas Instruments. With an output that has a voltage of 0 to 30 V, this is power management at its best. This current mode controller supports boost|flyback|forward topology. Its single PWM output produces a current of 200Max mA. 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 current mode controller"s maximum duty cycle is 48Typ %. This current mode controller has an operating temperature range of -40 °C to 85 °C. This device has a maximum of 30 V.
