UC2874DW-1G4 Overview
In the 18-SOIC (0.295, 7.50mm Width) package, the switching controller meets most application requirements. dc motor controller is suitable for 1 output generation. Tube solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). Voltages 9V~36V are the dc control's supply voltage and operating voltage, respectively. Suitable for a -25°C~85°C TA dc switcher. A switching controller such as this can switch at a value of Up to 300kHz . The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Soft Start. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. DUAL are the position of the terminal of the switching converters. Various 18 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. UC2874 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 18. Particularly, switching converter is a type of Switching Regulator or Controllers. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. There is a maximum frequency of 300kHz for this dc regulators. To operate the voltage regulator dc to dc safely and reliably, users should apply 36V. A value of 1A is output as the maximum value of current. In order to limit the voltage of a dc switcher whose maximum input voltage is 36V, it must be limited by the user. There must be a 4.5V supply voltage.
