TPS65283-1 Overview
The TPS65283, TPS65283-1 in thermally-enhanced 4-mm × 4-mm VQFN package is a full featured 4.5- to 18-V Vin, 3.5-A/2.5-A output current synchronous step down DC-DC converter, which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. The device also incorporates one N-channel MOSFET power switches for power distribution systems. This device provides a total power...
