4.5V 至 17V 输入、6A SWIFT™ 同步降压转换器 14-VQFN -40 to 150

Description

The TPS54620 in thermally enhanced 3.50 mm x 3.50 mm QFN package is a full featured 17 V, 6-A

synchronous step down converter which is optimized for small designs through high efficiency and

integrating the high-side and low-side MOSFETs. Further space savings are achieved through current

mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductor"s footprint.
