Output Specifications
The SPT5504Q is a member of Bourns’
ringing SLIC power module family. The
output voltages provide low-noise operation
for very quiet off-hook conditions and
on-hook transmissions. The SPT5504Q is
capable of 7 W total output power, with up
to 100 mA available from each output rail.
The part is available in a surface mount
configuration. The compact design
provides a small footprint, minimizing real
estate usage on the main board.
The SPT5504Q is a robust design that
meets the electrical and environmental
specifications for powering RSLICs. By
integrating the entire power solution, the
OEM customer saves time and money in
engineering, debugging, purchasing hardto-source components, test and inventory.

Although not specifically required for
proper/specified operation of the SPT5504Q,
external decoupling capacitors may be
employed to reduce noise and interaction
with adjacent circuits. Output decoupling
can be achieved by placing 0.1 µf ceramic
caps at the load. Note that larger cap values
can substantially increase the start-up
currents drawn from the 5 V source.

Input Decoupling
Local input decoupling is recommended to
reduce the apparent source impedance to
the SPT5504Q.
