MILLIMETERS (INCHES)DIMENSIONS = TOLERANCES = .25 (.01) (.xx) = ± .13 (.005) (.xxx) = ± Product Dimensions 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 hard- to-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 µf ceramic caps at the load. Input Decoupling Local input decoupling is recommended to reduce the apparent source impedance to the SPT5204Q. C2 0.1 µF , X7R ceramic C1 3 x 33 µF , 25 V, low ESR tantalum (AVX TPS series or Kemet T495 series). Fault Protection F1 may be used in distributed systems to isolate single-board failures. F1 should be ≥ 2 A, i2t ≥ 0.2 A2 sec, R ≥ 25 mΩ.
