Description
Current Mode PWM Controller -0.1V to 11V 1A 500kHz 8-Pin CDIP Tube
Detailed Description
If you are in need of a tool that can regulate the amount of voltage entering your external circuit, look no further than the UC1843AJ current controller from Texas Instruments. This current mode controller supports boost|flyback|forward topology. Its single PWM output produces a current of 1000(Max) 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 100 %. This device has a maximum of 30 V. This current mode controller has a minimum operating temperature of -55 °C and a maximum of 125 °C.
