BA9744FV-E2 Overview


In the 16-LSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 2 numbers. An enclosure of Tape & Reel (TR) is used to package the PMIC. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 2.5V~35V. Qualified to work in an dc switcher with -40°C~85°C TA. The switching controller is capable of switching at the 10kHz~800kHz position. A generalization of dc dc regulator can be made using Surface Mount. Featured in the dcdc regulator is Dead Time Control, Soft Start which allows efficient switching control. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. The 16 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 3V nominal DC switcher's voltage input. In addition to "BA9744", there are other relevant dc to dc converter ics you can find. In total, switching converter has 16 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. According to the test statistics, DC regulator outputs 35V voltage. normally, the dc dc regulator's output current is 30mA, which you should keep in mind when starting a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 65 % during power-up and power-down. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulator has a maximum frequency of 800kHz. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 35V.
