SI9122DQ-T1-E3 Overview


Capsuled in the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. This dc motor controller can be used to generate outputs with 1 numbers. 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). This dc control has a supply voltage and operating voltage of 10V~13.2V. Worked in a -40°C~85°C TA dc switcher before. A switching controller such as this can switch at a value of 500kHz . The Surface Mount allows it to be used for dc dc regulator in general. Current Limit, Sequencing, Soft Start is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of terminations with 20 of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. Other relevant dc to dc converter ics can be found by searching "SI9122". 20 pins are on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 3.3V voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 2.5mA. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 95 %. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. 750kHz is the maximum frequency of this dc regulators. When running the voltage regulator dc to dc in a circuit, users should apply 72V to ensure safety and reliability.
