SI9122EDQ-T1-E3 Overview


In the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. dc controls with 10.5V~13.2V voltage are supplied and operated. Qualified to work in a -40°C~85°C TA dc switcher. A switching controller such as this can switch at a value of 500kHz . The Surface Mount value makes it suitable for general dc dc regulator. Current Limit, Sequencing, Soft Start provides dcdc regulator efficient switching control. SWITCHING REGULATOR analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 20 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. In addition to "SI9122", there are other relevant dc to dc converter ics you can find. There are a total of 20 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. DC regulator's maximum frequency is 600kHz. For better satisfaction, the value of DC to DC voltage regulator is CAN ALSO BE CONFIGURED AS CURRENT MODE. When running the voltage regulator dc to dc in a circuit, users should apply 13.2V to ensure safety and reliability. A value of 1A is output as the maximum value of current.
