XR76205ELTR-F

开关稳压器 5A 40V Synchronous  Step Down COT Regulator

General Description  

The XR76205ELTR-F XR76203, XR76205 and XR76208 are synchronous step-down  regulators combining the controller, drivers, bootstrap diode and  MOSFETs in a single package for point-of-load supplies. The XR76203,  XR76205 and XR76208 have load current ratings of 3A, 5A and 8A  respectively. A wide 5V to 40V input voltage range allows for single  supply operation from industry standard 24V ±10%, 18V-36V, and  rectified 18VAC and 24VAC rails.
