4.5-V to 15-V input, dual 6-A, single 12-A, output power module with -55°C operating temperature

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.
