PTB48502A3.3/1.2-V 45-W Output, 48-V Input DC/DC Converter | DC DC Converters | 1 | NRND | The PTB4850x power modules are a dual-output isolated DC/DC converter, designed to provide the logic supply voltages for AC-7 based xDSL applications. The PTB48500 is rated for 13 A of total output current, making it suitable for 32-channel xDSL applications. The PTB48501 and PTB48502 provide output current for powering up to 64 xDSL channels. The PTB48501 is rated for 16.5 A total output current, and the PTB48502, 21 A. The PTB48502 incorporates 10 W of additional capacity for powering peripheral circuitry. Any of these converters can be used for other applications with similar power requirements.
The modules operate from a standard telecom (-48 V) central office (CO) supply and include anon/offenable control, output current limit, over-temperature protection, input under-voltage lockout (UVLO). The PTB48500 and PTB48501 also incorporates a power-up reset (POR) output.
The modules are designed to operate with one of the PTB4851x DC/DC converter modules. The combination of PTB4850x and PTB4851x converter provides the complete the power supply for an AC7 chipset. TheEN OutandSync Outpins provide compatible output signals for controlling both the power up sequence and switching frequency the PTB48510.
The PTB4850x modules employ double-sided surface mount construction, and are an industry standard size.

PTB48510C66-W +/- 15-V, Dual Complementary-Output DC/DC Converter | DC DC Converters | 3 | NRND | 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.
