MCP19122-E/MJ Overview


The switching controller fits in the 24-VFQFN Exposed Pad package and is ideal for most applications. There is sufficient capacity to generate switching controller for outputs 1. Packaging for the pmic consists of Tube solid enclosures. A total of PWM Signal dc switching's outputs can be handled by it. Voltages 4.5V~40V are the dc control's supply voltage and operating voltage, respectively. A -40°C~125°C TA dc switcher is not a problem. Switching can be done at 100kHz~1.6MHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Watchdog. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at QUAD . Different dc switching's functions can be applied to 24 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 40V volts. You can find other relevant dc to dc converter ics by searching "MCP19122". 4.5V should be the minimum input voltage for the dc dc voltage regulator. At most, the dc to dc regulator accepts 48V input voltage. Hence, 3V TO 5V REGULATING OUTPUT ALSO AVAILABLE is used to better suit the DC to DC voltage regulator's situation. There are several dc to dc voltage regulator in the Automotive, AEC-Q100 series.
