UC2874DW-2G4 Overview


Capsuled in the 18-SOIC (0.295, 7.50mm Width) package, the switching controller suits most application needs. This dc motor controller can be used to generate outputs with 1 numbers. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sDC control operates at 4.4V~36V volts and has 4.4V~36V supply voltage. Suitable for work in a -25°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 300kHz. dc dc regulator is made easier with Surface Mount. Soft Start is used for efficient switching control in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 18 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. UC2874 can be searched for other relevant dc to dc converter ics. 18 pins are on switching converter. Switching converter is a special type of Switching Regulator or Controllers. DC regulators have a maximum frequency of 300kHz. It is suggested that users apply 36V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. The dc switching utilizes 8.5mA when it is in a dormant state. The dc switcher's maximum input voltage is 36V; users must limit it accordingly. 10V is the required supply voltage. DC switcher will not be able to provide an output current above 500mA volts. At its maximum output, the switching converter can provide 30V volts. Neither the voltage controller's lowest voltage output 2.5Vr its highest voltage output is less than 2.5V.
