www.ti.com SLTS218C – SEPTEMBER 2003 – REVISED AUGUST 2006 DUAL-OUTPUT, 48-V INPUT ISOLATED DC/DC CONVERTER for xDSL
FEATURES DESCRIPTION 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. Dual Outputs (Independently Regulated)
