UC3843BN - ST Microelectronics Function Overview

●Varying voltages can be harmful to some microprocessor-based circuits. The UC3843BN current controller from STMicroelectronics is a great tool to modulate these levels to meet your requirements. This current mode controller supports boost|flyback topology. Its single PWM output produces a current of 1000(Max) mA. This part offers a switching frequency of 500 kHz in order to work properly. This current mode controller has a minimum operating temperature of 0 °C and a maximum of 70 °C. This current mode controller"s maximum duty cycle is 100 %. This device has a maximum of 30 V.
