Description

With this UCC38C44D current controller, developed by Texas Instruments, easily manage varying levels of output voltage entering your circuit. 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. This part offers a switching frequency of 1000 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 current mode controller has an operating temperature range of 0 °C to 70 °C. This device has a maximum of 18 V. This current mode controller"s maximum duty cycle is 50 %.
