TEXAS INSTRUMENTS TPS54620RGYR 芯片, 直流/直流转换器, 降压稳压器, 1.6MHZ, VQFN-14
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.
