The first two transformers in the series are designed for a forward converter DC-to-DC topology operating from a wide-range telecom input voltage of 36 to 72 volts. Part no. PA0457 provides a regulated output of 67 watts (3.3-volt 20-amp), while PA0458 yields 75 watts (5.0-volt / 15-amp). Other turns ratios can be made available for differing output voltages. Both transformers' SMT packages are compatible with all contemporary pick-and-place processes.
Technical Information
Turns ratios are 12:2 for part number PA0457 with a power rating of 67 watts and 12:3 for part number PA0458 with a power rating of 75 watts. Primary inductance is rated at a minimum 220 micro henries. The primary direct current rating (DCR) is rated at 108 milliohms, the primary auxiliary at 200 milliohms and the secondary at 1.3 or 3.0 milliohms, dependent on model number. An extended operating temperature range of -40 degrees Celsius to +125 degrees Celsius ensures product stability with minimum drift in a wide range of environmental conditions.
