BA9741FS-E2 Overview


With its 16-LSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. There is sufficient capacity to generate switching controller for outputs 2. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The program can handle Transistor Driver dc switching's outputs (s). A 3.6V~35V voltage is supplied to the dc control and used for operating it. Suitable for a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 10kHz~800kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Dead Time Control, Soft Start. An analog IC with the DUAL SWITCHING CONTROLLER signal 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. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 3.6V. Searching "BA9741" will return other relevant dc to dc converter ics. In total, switching converter has 16 pins. There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended to use 3.6V as the minimum input voltage of dc dc voltage regulator. DC regulator outputs 35V voltage according to the test statistics. You should note down the dc dc regulator's usual output current of 100mA when you start a project. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. Switching controller operates at a frequency of 480kHz. To operate the voltage regulator dc to dc safely and reliably, users should apply 35V.
