Описание
Protecting your components from voltage spikes is important in any electronics circuit. STMicroelectronics&s; UC2844BN current controller can help you regulate these changes. This current mode controller supports boost|flyback 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&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&s;s maximum duty cycle is 50 %. This current mode controller has an operating temperature range of -25 В°C to 85 В°C. This device has a maximum of 30 V.
