可编程的,脱线, PWM控制器 Programmable, Off-Line, PWM Controller
Generate and regulate a stable current with this current controller by Texas Instruments. This current mode controller supports boost|buck|flyback|forward topology. It has single PWM output. 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 46 %. This current mode controller has a minimum operating temperature of -40 °C and a maximum of 85 °C.
