General Information
The SPT5204QL is a member of Bourns
Switch Power ringing SLIC power module
family. The output voltages provide lownoise operation for very quiet off-hook
conditions and on-hook transmissions. The
SPT5204QL 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 SPT5204QL 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.
Fault Protection
Although not specifically required for
proper/specified operation of the
SPT5204QL, 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.

should be ≥ 2 A, i2t ≥ 0.2 A2 sec,
R ≤ 25 mΩ.
Input Decoupling
Local input decoupling is recommended to
reduce the apparent source impedance to
the SPT5204QL.
