SI9122ADQ-T1-E3 Product Details
SI9122ADQ-T1-E3 Overview
In the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. There is a Tape & Reel (TR) solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 10.5V~13.2V volts and has 10.5V~13.2V supply voltage. Suitable for working in an dc switcher that has a -40°C~85°C TA. It can switch at 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Current Limit, Sequencing, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 20 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. In addition to "SI9122", there are other relevant dc to dc converter ics you can find. There are 20 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended that the dc dc voltage regulator's minimum input voltage be 28V. The dc to dc regulator can only accept 75V input voltage. DC regulator750kHz has the maximum frequency. As a result, switching converter outputs current to the greatest value possible (1A).
