In summary, the TPS84620 is an integrated power solution which incorporates a power inductor that is optimized for the 6A DC/DC converter. The IC, inductor, and passive components are reflow soldered to a metal lead frame. Application of the TPS84620 is very easy, requiring only three external components; an input capacitor, an output capacitor, and a voltage programming resistor. Other features are available to allow the same flexibility as a discrete solution; such as an adjustable switching frequency, an adjustable soft start, an adjustable under voltage lock out, a sequencing pin, and a clock pin to synchronize the frequency to a master clock. These capabilities require additional external components. The TPS84620 is a small 12V, 6A solution, and the 15 x 9 x 2.8mm package helps save board space. Even with the integrated power inductor integrated, the package power dissipation is significant.  The low thermal resistance translates into better long term reliability as the device operates at a lower temperature.
