TL494CDR Overview
This switching controller fits most application requirements since it is packaged in a 16-SOIC (0.154, 3.90mm Width) package. It is sufficient to generate 2 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Cut Tape (CT) rating. A total of Transistor Driver dc switching's outputs can be handled by it. 7V~40V is the supply voltage and the operating voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. This switching controller can switch at 1kHz~300kHz. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Dead Time Control, Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 16 terminations with a variety of function. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. A DC switcher's nominal voltage of 15V is input. You can find other relevant dc to dc converter ics by searching "TL494". The switching converter has a total of 16 pins. In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 7V as the minimum input voltage of dc dc voltage regulator. Statistically, the DC regulator outputs 40V voltage. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 45 %. There is 300kHz frequency setting on the switching controller. Dormant dc switchings use 7.5mA. There must be a voltage supply of 15V volts.
