Chipsets
The A-suffix module (±5 V) is designed to power the

STAND-ALONE APPLICATION
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,
Enable
and
Sync
In,
are
compatible with the EN Out and Sync Out signals 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.
