SPT5204Q SLIC Power Module
Input Specifications
Voltage ......................................10 VDC Min. 12 VDC Nom. 15 VDC Max. Current (at 12 Vin) No Load................................52 mA Nom. 60 mA Max. IBAT1 = 100 mA ...................860 mA Nom. 900 mA Max. IBAT2 = 100 mA ...................320 mA Nom. 350 mA Max.
General Information
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 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.

Output Decoupling
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 f ceramic caps at the load.
Fault Protection
F1 F1 may be used in distributed systems to isolate single-board failures. should be 2 A, i2t 0.2 A2 sec, R 25 m.
Input Decoupling
Local input decoupling is recommended to reduce the apparent source impedance to the SPT5204Q. C2 0.1 F, X7R ceramic C1 3 x 33 F, 25 V, low ESR tantalum (AVX TPS series or Kemet T495 series).
