The PTB48580 series of isolated DC/DC converter modules produce a complementary pair of regulated supply voltages for powering line-driver ICs in xDSL telecom applications. The modules operate from a standard telecom (–48 V) central office (CO) supply and can provide up to a 30 W of power in a balanced load configuration.

The A-suffix module (±5 V) is designed to power the line driver ICs for the AC-7 ADSL chipset. Other voltage options will power other analog applications requiring a complementary supply with relatively balanced loads. The outputs can also be easily configured for single-ended use.

The modules incorporate an On/Off enable control, output current limit, over-temperature protection, and input under-voltage lockout (UVLO) as standard features.

The control inputs, "Enable" and "Sync In," are compatible with the "EN Out" and "Sync Out" signals of the PTB48500 DC/DC converter. This allows the power-up and switching frequency of the PTB48580 series to be directly controlled from a PTB48500. Together a PTB48500 and a PTB48580A converter meet all the system power and sequencing requirements of an AC-7 ADSL chipset.

The PTB48580 series uses doublesided surface mount contruction. The package size is based on an industry standard outline and does not require a heatsink. Both through-hole and surface mount pin configurations are available.
