TL494CDR2 Overview
In the 16-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. The pmic is packaged in Tape & Reel (TR) solid enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 7V~40V and has a 7V~40V supply voltage. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. With this switching controller, you can switch at 200kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Dead Time Control, Frequency Control is included in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. There are many different types of terminations for 16. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "TL494". Switching converter has a total of 16 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. 7V should be the minimum input voltage for the dc dc voltage regulator. Considering the dc to dc regulator can only accept 40V input voltage, it is important to take note of this. If you start a project, note down the dc dc regulator's usual output current of 500mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 48 %. Switching controllers operate at 40kHz frequencies. It is suggested that users apply 15V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. Thare are switch converters of the SWITCHMODE? series.
