3 Description
The TPS50301-HT is a 6.3-V, 3-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 a high switching
frequency, reducing the inductor's footprint. The
devices are offered in a thermally enhanced 20-pin
ceramic, dual in-line flatpack package.
