UC2842ADTRG4 Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. There are Transistor Driver dc switching's output (s) that it can handle. A 10V~30V voltage is supplied to the dc control and used for operating it. Qualified to work in a -40°C~85°C TA dc switcher. There is a switch at Up to 500kHz that can be used with this controller. A generalization of dc dc regulator can be made using Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of dc switching's functions can be performed on 14 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC2842". Pins number 14 of switching converter in total. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 15V voltage based on test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. Switching controllers operate at 450kHz frequencies. It is possible to set the input voltage as 25V for nominal working statuses.
