UC2843BDR2 Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 1 output generation. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) are supported. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with -25°C~85°C TA. It can switch at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. An array of 14 terminations of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. UC284*B can be searched for other relevant dc to dc converter ics. There are only 14 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Statistically, the DC regulator outputs 5.05V voltage. A maximum voltage of 25V is accepted by the dc to dc regulator as an input voltage. You should note that the dc dc regulator's usual output current is 1A. The duty cycle of the voltage regulator dc to dc can be set to 96 % on power-up or power-down to ensure reliability. DC regulators have a maximum frequency of 275kHz. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 30V.
