XR77128ELBTR-F Product Details
XR77128ELBTR-F Overview
In the 44-WFQFN Exposed Pad package, the switching controller meets most application requirements. It is sufficient to generate 4 outputs with this dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. There are Transistor Driver dc switching's output (s) that it can handle. 5.5V~25V is the operating voltage and supply voltage of the dc control. A -40°C~125°C TJ dc switcher is not a problem. Switching can be done at 105kHz~1.23MHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable which allows efficient switching control.
