RT8228BGQW Overview


With its 12-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For 1 outputs, the dc motor controller is appropriate. There is a Tape & Reel (TR) solid enclosure around the pmic. The program can handle Transistor Driver dc switching's outputs (s). Voltages 4.5V~5.5V are the dc control's supply voltage and operating voltage, respectively. Worked in a -40°C~85°C TA dc switcher before. The Surface Mount makes it ideal for general dc dc regulator. Current Limit, Enable, On Time Control, Phase Control, Power Good provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Switching converters are designed with the terminal (s) at position QUAD . The 12 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 5V volts. There are a total of 12 pins on switching converter. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Statistically, DC regulator outputs 3.3V volts. It should be noted that the dc to dc regulator only accepts 5.5V voltage as input voltage. Switching controller operates at 200kHz Hz.
