Description

The PTB4851x series of isolated DC/DC converter modules produce a complementary pair of regulated supply voltages for powering line-driver devices in xDSL telecom applications. The modules operate from a standard telecom (–48 V) central office (CO) supply and can provide up to a 72 W of power in a balanced load configuration. The A-suffix module (±5 V) is designed to power the line driver devices for the AC-7 ADSL chipset. Other voltage options powers other analog applications requiring a complementary supply with relatively balanced loads.o Both the PTB48510 and PTB48511 include an "on/off" enable control, output current limit, over-temperature protection, and input under-voltage lockout (UVLO). The PTB48511 adds output overvoltage protection (OVP). The control inputs,EnableandSync In, are compatible with theEN OutandSync Outsignals of the PTB48500 DC/DC converter. This allows the power-up and switching frequency of the PTB4851x modules to be directly controlled from a PTB48500. Together the PTB48500 and PTB4851xA converters meet all the system power and sequencing requirements of the AC-ADSL chipset. The PTB4851x uses double-sided surface mount technology contruction. The package size is based on the industry standard outline and does not require a heatsink. Both through-hole and surface mount pin configurations are available.
