Описание
This L5991D current controller by STMicroelectronics is perfect for current which needs to be supplied to an external system. This current mode controller supports boost|flyback topology. Its single PWM output produces a current of 1500(Max) mA. This part offers a switching frequency of 1000 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 -40 В°C to 150 В°C. This current mode controller&s;s maximum duty cycle is 93(Min) %. This device has a minimum operating supply voltage of 12 V and a maximum of 20 V.
