PRODUCT OVERVIEW
The 3D PLUS 3DPM0289 PoL DC/DC Converter module operates over a wide input voltage range (4.5V
to 12.0V) and provides up to 2A of output current with an output voltage range of 1.0V to 5.0V. The
module has a small form factor, which makes possible to bring the PoL close to the components to be
powered in order to limit the voltage drop.
Based on a Buck topology, the PoL module uses
synchronous rectification to boost efficiency higher
than 90% (3.3V/from 0.3A to 1.5A). Switching
frequency is fixed at 340 kHz. EMC filters are
integrated to simplify module implementation and
output voltage is adjustable through an external
resistor. Module is fully protected against output
overload, input under-voltage and internal overtemperature.
For increased output current, two PoL modules can
operate in parallel configuration to achieve up to 4A.
No external component needs to be added. Only PWS
pins must be connected together enabling an equitable
sharing of the current between the two PoL.
The 3DPM0289-1 PoL Converter is an ITAR Free
product that features a SEL LET of 60 MeV.cm2/mg
and a TID threshold of 40krad (Si).
The PoL Converter is an excellent solution for low voltage power distribution systems designed around
high-speed digital electronics such as ASICs, FPGAs (ACTEL, XILINX,…) and memories (SDRAM, DDR,
DDR2, DDR3,…). Also, it can be used for any other high efficiency Point of Load regulation / distributed
power systems for other space applications: science and deep space missions, Earth observation,
navigation, launchers and manned space vehicles.
