DESCRIPTION
SLTS218C – SEPTEMBER 2003 – REVISED AUGUST 2006
DUAL-OUTPUT, 48-V INPUT ISOLATED DC/DC CONVERTER for xDSL
Dual Outputs (Independently Regulated)
The PTB4850x power modules are a dual-output
isolated DC/DC converter, designed to provide the
Input Voltage Range: 36 V to 75 V
logic
supply
voltages
for
AC-7
based
xDSL
Power-Up/Down Sequencing
applications. The PTB48500 is rated for 13 A of total
1500 VDC Isolation
output current, making it suitable for 32-channel
Over-Current Protection
xDSL applications. The PTB48501 and PTB48502
provide output current for powering up to 64 xDSL
Over-Temperature Shutdown
channels. The PTB48501 is rated for 16.5 A total
Under-Voltage Lockout
output current, and the PTB48502, 21 A. The
Fixed Frequency Operation
PTB48502 incorporates 10 W of additional capacity
for powering peripheral circuitry. Any of these
Temp Range: –40
°C to 85°C
converters can be used for other applications with

lockout (UVLO). The PTB48500 and PTB48501 also
– UL/cUL 60950
incorporates a power-up reset (POR) output.
– EN 60950
The modules are designed to operate with one of the

DC/DC
converter
modules.
The
combination of PTB4850x and PTB4851x converter
provides the complete the power supply for an AC7
chipset. The EN Out and Sync Out pins 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.
