UC2845BD Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. 1 outputs can be generated with the dc motor controller. There is a Tube solid enclosure around the pmic. The system can process Transistor Driver dc switching's outputs (s). 7.6V~30V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -25°C~85°C TA rating. Using this switching controller, it is possible to switch at 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. The 14 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "UC284*B". There are a total of 14 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. As determined by the test statistics, the output voltage of DC regulator is 5.05V. Voltages 25V are the maximum that the dc to dc regulator will accept. You should note down the dc dc regulator's usual output current of 1A when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 48 %. This dc regulatorhas a max frequency of 275kHz. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 30V.
