Output Specifications
The SPT5204Q 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
SPT5204Q 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
Output Decoupling
provides a small footprint, minimizing real
estate usage on the main board.
The SPT5204Q 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
SPT5204Q, 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.

Input Decoupling
Local input decoupling is recommended to
reduce the apparent source impedance to
the SPT5204Q.
