UC3842BDR2 Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is enough capacity in the dc motor controller to generate the output for the 1 input. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's10V~30V is the supply voltage and the operating voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. The switching controller is capable of switching at the Up to 500kHz position. dc dc regulator is made easier with Surface Mount. Frequency Control is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. switching converters terminal (s) are designed to be at DUAL. 14 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. It should be noted that the dc to dc regulator only accepts 25V voltage as input voltage. As a result, switching converter outputs current to the greatest value possible (1A).
