Tyco Electronics Power Systems proclaims its PIM200x series of power input modules as the first in the industry to comply with the Advanced Telecom Computing Architecture (advancedtca) specifications. As such, the first two of these high-efficiency (up to 97 percent) off-the-shelf modules, the PIM200F (3.3Vdc out for power management circuits) and PIM200A (5Vdc) greatly reduce system complexity and the product time-to-market. They provide a total power-management solution when combined with the company's isolated dc-dc, bus and point-of-load converters for board-level management.

The modules, placed between dual-input DC power sources and an isolated 48V-to-12V dc-dc converter (which thence feeds a given system's point-of-load converters) deliver up to 200W from a -38Vdc to -75Vdc input, and thus are suitable for both -48Vdc and -60Vdc power distribution. The PIM modules incorporate all of the power management features required by the AdvancedTCA PICMG 3.0 specification. These features include hot plug capabilities and OR-ing functionality, A/B feed loss alarm, EMI filter to meet Class B CISPR specs, and 8W of auxiliary power (at 3.3V/5V) for IPMI and house keeping functions. Inrush current limiting, and under-voltage, over-voltage, over-current and thermal protection are standard. The PIM200x modules also provide a charging current at 72Vdc for external holdup/energy storage bulk capacitors. MTBF is 1 million hours (typical), as per Telcordia specs. The modules are UL, CSA, VDE and CE approved.

The PIM200x modules, which measure 2.78-by-1.45-by-0.5 inches, are priced at $41.20 each in 1,000 quantities. Samples are already available.
