XR77129ELB-F Overview

For outputs of 4, this dc motor controller is suitable. This switching controller can switch at 1.23MHz. 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 . Various 44 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 12V. It is recommended to use 6V as the minimum input voltage of dc dc voltage regulator. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN PFM CONTROL TECHNIQUE, OUTPUT VOLTAGE RANGE FROM 0.6 V TO 5.5 V. At -40°C and above, dc regulator should be kept. At a temperature around 125°C degrees Celsius, dc regulator should be running. The switch converters have 1 function (s) in total. The controller switches with phase number 1.
