UC3845DR2 Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. It is sufficient to generate 1 outputs with this dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Suitable for a 0°C~70°C TA dc switcher. The switching controller can be switched at 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of 14 terminations are available in dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. In addition to "UC384*", there are other relevant dc to dc converter ics you can find. There are 14 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 8.2V. According to the test statistics, DC regulator outputs 5.1V voltage. Considering the dc to dc regulator can only accept 25V input voltage, it is important to take note of this. Switching controllers operate at 275kHz frequencies. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 30V. A maximum value of 1A is output for current. In dormant mode, 500μA is used.
