Dual-Output, 48-V Input Isolated DC/DC Converter For XDSL

The PTB4850x Power Modules are a dual-output isolated DC/DC converter, designed to provide the Logic supply volt- ages 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 chan- nels. 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 periph- eral circuitry. Any of these converters CAN be used for other applications with simi- lar power requirements. The modules operate from a standard telecom (-48 V) central office (CO) supply and include an on/off enable 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 con- verter modules. The combination of a PTB4850x and PTB4851x converter provides the complete the power supply for an AC7 chipset. The EN Out and Sync Out pins provide compatible out- put signals for controlling both the power up sequence and switching frequency of the PTB48510. The PTB4850x modules employ double-sided surface mount construction, and are an industry standard size. By Texas Instruments
