3 Description
The TPSM5D1806E dual 6-A output power module is
a highly integrated and flexible DC-DC power supply
packaged in a compact 8-mm × 5.5-mm × 1.8-mm
QFN package. The input voltage range of 4.5 V to
15 V allows conversion from a wide intermediate
bus as well as standard 5-V and 12-V rails. The
two 6-A outputs can be configured independently for
two separate power rails or combined for a single
2-phase, 12-A output.
The low-profile, 51-pin QFN package with optimal
package layout enhances thermal performance. The
enhanced temperature performance of –55°C enables
aerospace applications in environments such as
outside cabin-mounted modules or flight control units.
The package footprint has all signal pins accessible
from the perimeter and large thermal pads beneath
the device for simple layout and easy handling in
manufacturing.
The integrated power design eliminates the loop
compensation and magnetics part selection from
the design process. The device offers independent
enable control and power-good signal for each output.
Switching frequency and phase offsetting can be
configured using pin-strapping. The device also offers
overcurrent and thermal shutdown protection.
