Thermal Considerations
dissipation of the NCP5810D. The power dissipation is a
function of efficiency and output power. Hence, increasing
the output power requires better components selection. For
example, should one change inductors: larger inductor
value (in micro Henri) and/or lower DCR may improve
efficiency. Adding the optional Schottky diode D2
provides a lower drop when the current flowing from the
inductor to the load, thereby improving the boost converter
efficiency.
to the ground plane to used the PCB as a heatsink. This
ground should then be connected to an internal copper
ground plane with thermal via placed directly under the
package to spread out the heat dissipated by the NCP5810D
as depicted in Figure 18.
Careful attention must be paid to the internal power
