UC1843AVTD1 Product Details

UC1843AVTD1 Overview


This switching controller can switch at 500kHz. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the UPPER position. 22 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. Switching converter has a total of 0 pins. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 100 %. It is suggested that users apply 30V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. DC regulator should be kept at a temperature of 25°C or higher. DC regulator should run at a temperature of 25°C more than 25°C degrees Celsius. The switch converters have 1 function (s) in total. It is ideal for switching controllers with 1A input. Normally, it outputs a value of 5V.
