Technical Reference Notes APC12 Centauri II Centauri II (APC12) Non-Isolated DC/DC Power Module Tiny SMT Footprint – 1.8V-12V Input, 0.9V to 3.6V Output PRELIMINARY The APC12 Centauri II series is Astec’s recent addition to its non-isolated SMT POL line. With the wide acceptance of it’s predecessor (APC08 series) and the continuous system requirement for higher load current, the Centauri platform have been revolutionized to provide 12A load current from it’s original 8A device. The APC12 offers the same standard features common to the Centauri Product Line: wide input voltage range; wide output voltage range; high efficiency; Positive Output Enable; Power Good signal and Current Sharing. It also adapts the same Centauri SMT footprint for optimum user flexibility and multiple sourcing. The APC12 also comes with an output Trim pin, which allows output adjustment from 0.9V to 3.6V through external resistance programming. It works from a wide input voltage range of 1.8V to 13V and offers an extensive array of output voltages starting from 0.9V to 3.6V. It is ideal for Point of Load applications and provides the most flexibility for the ever-changing DSP and ASIC power requirements.
