TL494CD Overview
Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 2 outputs with this dc motor controller. PMIC is packaged in a solid enclosure of Tube. It is capable of handling Transistor Driver dc switching's outputs (s). 7V~40V is the operating voltage and supply voltage of the dc control. Suitable for work in a 0°C~70°C TA dc switcher. This switching controller can switch at 200kHz. The Surface Mount makes it ideal for general dc dc regulator. Dead Time Control, Frequency Control provides dcdc regulator efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. 16 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis 15V volts. A search for "TL494" will reveal other relevant dc to dc converter ics. There are a total of 16 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. This dc dc voltage regulator should be powered by a voltage of 7V. The dc to dc regulator can only accept a maximum input voltage of 40V. You should note that the dc dc regulator's usual output current is 500mA. A duty cycle set at 48 % ensures voltage regulator dc to dc reliability during power-on and power-off. This dc regulatorhas a max frequency of 200kHz. A circuit should contain 15V in order to ensure the voltage regulator dc to dc runs safely and reliably. A dc to dc voltage regulator in the SWITCHMODE? series, it belongs to this family.
