If you need to regulate the level of voltage entering your circuit, the UCC38083P current controller from Texas Instruments is your solution. This current mode controller supports boost|buck|half-bridge|push-pull topology. Its 2 PWM outputs produce a current of 1000(Max) mA. It has a switching frequency of 50 to 1000 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 device has a maximum of 15 V. This current mode controller"s maximum duty cycle is 50 %. This current mode controller has an operating temperature range of 0 °C to 70 °C.
