BA9741F-E2 Overview


It comes in the 16-SOIC (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 2 outputs. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 3.6V~35V. Qualified to work in a -40°C~85°C TA dc switcher. The switching controller can be switched at 10kHz~800kHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Dead Time Control, Soft Start is included in the dcdc regulator. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. Different dc switching's functions can be applied to 16 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 3.6V. Searching "BA9741" will return other relevant dc to dc converter ics. In total, switching converter has 16 pins. Switching converter is a type of Switching Regulator or Controllers in particular. The minimum input voltage of the dc dc voltage regulator should be 3.6V. DC regulator outputs 35V voltage based on test statistics. In most cases, the output current of the dc dc regulator will be 100mA, so note that when you start the project. The duty cycle of the voltage regulator dc to dc can be set to 65 % on power-up or power-down to ensure reliability. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controllers work at 480kHz Hz. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 35V. Output current will not exceed 100mA.
