UC3874DW-1 Overview

With a 18-SOIC (0.295, 7.50mm Width) package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 9V~36V. Suitable for a 0°C~70°C TA dc switcher. The switching controller can be switched at Up to 300kHz. 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 Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 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. Search for "UC3874" to find other relevant dc to dc converter ics. There are a total of 18 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. This Surface Mount makes DC switcher suitable for most prototypes and applications. This dc regulatorhas a max 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. 1A is the largest value switching converter outputs.
