UC2845AD8 Product Details
UC2845AD8 Overview
It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 1. Packaging for the pmic consists of Tube solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sVoltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Worked in a -40°C~85°C TA dc switcher before. With this switching controller, you can switch at 500kHz. A generalization of dc dc regulator can be made using Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. DUAL are the position of the terminal of the switching converters. A variety of terminations with 8 of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Search for "UC2845" to find other relevant dc to dc converter ics. 8 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Test statistics indicate DC regulator outputs 15V voltage. You should note that the dc dc regulator's usual output current is 1A. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. 450kHz is the frequency of the switching controller. For nominal working status, the input voltage can be set as 25V. The supply voltage should be 11V. Current supplied to the controller should not exceed 25mA.
