Power Supply for CompactPCI Systems
TTX Series are available in the following models: A 48 V DC input, 400 W, 3U, 1-slot with outputs of (5 V @ 35 A), (3.3 V @ 45 A), (12 V @ 5 A) and (-12 V @ 1.5 A). A 48 V DC input, 700 W, 6 U, 1-slot with outputs of (5 V @ 60 A), (3.3 V @ 90 A), (12 V @ 7.5 A) and (-12 V @ 1.5 A).
The new topology is an isolated, fixed 500 kHz switching frequency that utilizes dual soft switching bridge architecture with integrated planar magnetics. Voltage percentages and load balancing can also be verified. The I2C interface adds to the controllability by providing actual output voltages and current measurements; no guesswork is needed as with simple status bits. The main system CPU can provide look-ahead health assessment for early warnings of imminent failure, faulty connectors and other latent problems before they become critical.
