                                                XR77128ELBMTR-F Overview
The switching controller fits in the 44-WFQFN Exposed Pad package and is ideal for most applications. This dc motor controller can be used to generate outputs with 4 numbers. The pmic is packaged in Tape & Reel (TR) solid enclosure. The system can process Transistor Driver dc switching's outputs (s). 5.5V~25V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. The switching controller is capable of switching at the 105kHz~1.23MHz position. dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by Enable.
