General Description

The XR3902 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 4A peak output current over a wide input supply range, with excellent load and line regulation. The XR3902 requires a minimal number of readily available, external components and is available in a space saving ESOP8 package.
