With the UCC38C43D 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 18(Max) V, this is power management at its best. This current mode controller supports boost|buck|flyback|forward topology. Its single PWM output produces a current of 200(Max) mA. You can operate this at a switching frequency of 1000 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 18 V. This current mode controller"s maximum duty cycle is 100 %. This current mode controller has a minimum operating temperature of 0 °C and a maximum of 70 °C.
