General Information
The SPT5504C is a member of Bourns
Switch Power SLIC Power module family.
The output voltages provide low-noise
operation for very quiet off-hook conditions
and on-hook transmissions. The SPT5504C
is capable of 7 W total output power, with
up to 100 mA available from each output
rail.
The SPT5504C’s easy to use surface
Output Decoupling
Although not specifically required for
proper/specified operation of the
SPT5504C, 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 SPT5504C.
C2 0.1 µF, X7R ceramic
C1 100 µF, 10 V, low ESR tantalum (AVX
TPS series or Kemet T495 series).
mount design and compact footprint
minimize the board space dedicated to
power (less than 1.4 in²). Its robust design
ensures reliable power and eliminates the
need for Aluminum Electrolytic capacitors.
By integrating the entire power solution, the
OEM customer saves time and money in
engineering, debugging, purchasing hard-
to-source components, test and inventory.
Fault Protection
F1 may be used in distributed systems to
isolate single-board failures.
F1 should be ≥ 2.5 A, i²t ≥ 0.2 A² sec,
R ≤ 25 mΩ.
