The 3DPM0289-1 PoL DC/DC Converter, operates over a wide input voltage range (4.5 V to 12 V) and provides up to 1.9 A of output current with an output voltage range of 1 V to 5 V.
Based on a Buck topology, the PoL module uses synchronous rectification to boost efficiency higher than 90% (3.3 V/0.3 A to 1.5 A). 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. Featuring specific radiation effect mitigation techniques and utilizing space design de-rating rules, the PoL Converter features a SEL LET threshold of 60 Mev.cm2/mg and a TID of 40 krad (Si).
The 3DPM0289 module is based on 3D PLUS’s stacking technology – which is qualified for harsh environments (able to withstand appreciable mechanical shock and vibration) – and also leverages 3D PLUS’s extensive experience in Space product design and component selection, yielding a highly reliable, Space qualified PoL with unprecedented power density and efficiency.
