BD9851EFV-E2 Overview


With its 20-VSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 2 outputs. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). Voltages 4V~18V are the dc control's supply voltage and operating voltage, respectively. A -40°C~85°C TA dc switcher is not a problem. The switching controller can be switched at 10kHz~3MHz. A generalization of dc dc regulator can be made using Surface Mount. Enable, Frequency Control, Soft Start is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. The switching converters's terminal (s) are designed at DUAL . Different dc switching's functions can be applied to 20 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. You can find other relevant dc to dc converter ics by searching "BD9851". In total, switching converter has 20 pins. The type is a particular Switching Regulator or Controllers of switching converter. An input voltage of 4V is the minimum required for the dc dc voltage regulator. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. This dc regulatorhas a max frequency of 3MHz. To run the voltage regulator dc to dc safely and reliably, users should apply 18V to the voltage regulator dc to dc.
