TL494BD Overview
Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 2. Tube is the solid enclosure in which PMIC is packaged. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 7V~40V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. This switching controller can switch at 200kHz. The Surface Mount allows it to be used for dc dc regulator in general. Dead Time Control, Frequency Control is used for efficient switching control in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. DUAL are the position of the terminal of the switching converters. There are many different types of terminations for 16. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. In addition to "TL494", there are other relevant dc to dc converter ics you can find. There are only 16 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Input voltage of dc dc voltage regulator must be 7V. The dc to dc regulator can only accept a maximum input voltage of 40V. The dc dc regulator's usual output current is 500mA, which should be noted down when you start a project. voltage regulator dc to dcs with a 48 % duty cycle are designed to be reliable when powered on and powered off. DC regulator's maximum frequency is 200kHz. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 15V. Basically, it's a dc to dc voltage regulator from the SWITCHMODE? series.
