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.
