Описание
This UC3843AN current controller by Texas Instruments is perfect for current which needs to be supplied to an external system. This current mode controller supports boost|buck|flyback|forward topology. Its single PWM output produces a current of 1000(Max) mA. This part offers a switching frequency of 500 kHz in order to work properly. In order to ensure parts aren&s;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 В°C to 70 В°C. This current mode controller&s;s maximum duty cycle is 100 %. This device has a maximum of 30 V.
