UC2874DW-2 Overview
The switching controller fits in the 18-SOIC (0.295, 7.50mm Width) package and is ideal for most applications. dc motor controller is suitable for 1 output generation. PMIC packaging is solid with a Tube enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 4.4V~36V and has a 4.4V~36V supply voltage. Worked in an dc switcher with a -25°C~85°C TA rating. The switching controller is capable of switching at the Up to 300kHz position. Surface Mount makes it suitable for general dc dc regulator. To provide efficient switching control, Soft Start is included in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. The 18 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. There is a DC switcher's nominal voltage of 12V. Other relevant dc to dc converter ics can be found by searching "UC2874". 18 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. It is estimated that this dc regulatorhas a maximum frequency of 300kHz. In dormant mode, 8.5mA is used. The maximum input voltage of dc switcher is 36V, so users should limit their voltage accordingly. 10V is the required supply voltage. A dc switcher can only produce an output current of 500mA. Datasheets indicate that the switching converter can output 30V volts at its maximum. Its lowest voltage output is not less than 2.5V.
