UCC3805DG4 Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sVoltages 3.6V~12V are the dc control's supply voltage and operating voltage, respectively. Worked in a 0°C~70°C TA dc switcher before. This switching controller can switch at 31kHz. dc dc regulators can be carried out with Surface Mount. To provide efficient switching control, Frequency Control is included in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at DUAL. An array of 8 terminations of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. 10V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "UCC3805". There are only 8 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. According to the test statistics, DC regulator outputs 5V voltage. You should note that the dc dc regulator's usual output current is 1A. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controller operates at a frequency of 1MHz. This voltage controller requires a supply voltage of 10V. The dc switcher will not provide an output current greater than 500μA. 25mA more than 25mA current should be supplied to the controller. 500μA current flow input could be used to operate the switching converter .
