MILLIMETERS (INCHES)DIMENSIONS = TOLERANCES = .25 (.01) (.xx) = ± .13 (.005) (.xxx) = ± Product Dimensions 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 mount design and compact footprint minimize the board space dedicated to power (less than 1.4 in 2). 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. 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). 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.
