3. Explanation

TPS50301-HT is a 6.3V, 3A synchronous step-down converter. This device has been optimized for small designs through high efficiency and integration of high and low side MOSFETs. Reduce the number of components through current mode control, and further save space by reducing the size of inductor packaging through high switching frequency. This device provides a heat-resistant enhanced 20 pin ceramic, dual inline flat package.
