SI9140DQ-T1-E3 Overview


It comes in the 16-TSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. There is a Tape & Reel (TR) solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. 3V~6.5V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with -40°C~85°C TA. With this switching controller, you can switch at 20kHz~2MHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the DUAL position. Different dc switching's functions can be applied to 16 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 5V. Searching "SI9140" will return other relevant dc to dc converter ics. Total pins of switching converter are 16. Switching converter type is specifically Switching Regulator or Controllers. It is recommended to use 3V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator can only accept 6.5V input voltage. In most cases, the dc dc regulator's output current is 380mA. This information should be noted when you begin working with the component. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulator2MHz has the maximum frequency. For better satisfaction, the value of DC to DC voltage regulator is IT ALSO OPERATES IN CURRENT MODE.
