Safely supply current to an external circuit by using this UCC2891PW current controller by Texas Instruments. Its typical operating supply voltage is 12 V. Its single PWM output produces a current of 2000 mA. This current mode controller supports flyback|forward topology. It has 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 current mode controller's maximum duty cycle is 73 %. This current mode controller has an operating temperature range of -40 °C to 105 °C. This device has a typical operating supply voltage of 12 V. Its minimum operating supply voltage of 8.5 V, while its maximum is 14.5 V.
