3 Description
The TPSM84209 power module is an easy-to-use
integrated power supply that combines a 2.5-A
DC/DC converter with a shielded inductor and
passives into a low-profile QFN package. This total
power solution allows as few as four external
components while maintaining an ability to adjust key
parameters to meet specific design requirements.
The wide input voltage range and small package size
of the TPSM84209 makes the device an excellent fit
for power rails that require up to 2.5 A of output
current.
The QFN package is easy to solder to a printed
circuit board and has excellent power dissipation
capability. The TPSM84209 offers flexibility with
many features and is ideal for powering a wide range
of devices and systems.
