TL494CDBRG4 Overview
This switching controller fits most application requirements since it is packaged in a 16-SSOP (0.209, 5.30mm Width) package. This dc motor controller can be used to generate outputs with 2 numbers. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 7V~40V. 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 1kHz~300kHz. dc dc regulator can be generalized using Surface Mount. For efficient switching control, the dcdc regulator features Dead Time Control, Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . Various 16 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. A search for "TL494" will reveal other relevant dc to dc converter ics. Pins number 16 of switching converter in total. 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. DC regulator outputs 40V voltage according to the test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. Voltage regulator dc to dc is designed to operate at 45 % duty cycle during power-ups and power-downs to ensure reliability. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. Switching controllers operate at 300kHz frequencies.
