SIP Non-Isolated dc-dc Power Modules:
Test Configurations
Note: Measure input reflected ripple current with a simulated source
inductance (L
TEST
) of 1μH. Capacitor CS offsets possible bat-
tery impedance. Measure current as shown above.
Figure 15. Input Reflected Ripple Current Test Setup.
Note: Scope measurements should be made using a BNC socket,
with a 10 μF tantalum capacitor and a 1 μF ceramic capcitor.
Position the load between 51 mm and 76 mm (2 in and 3 in)
from the module
Figure 16. Peak-to-Peak Output Ripple Measurement
Test Setup.
Note: All voltage measurements to be taken at the module termi-
nals, as shown above. If sockets are used then Kelvin con-
nections are required at the module terminals to avoid
measurement
errors due to socket contact resistance.

Design Considerations
Input Source Impedance
To maintain low-noise and ripple at the input voltage, it is
critical to use low ESR capacitors at the input to the module.
18 shows the input ripple voltage (mVp-p) for various output
models using a 150 μF low ESR polymer capacitor (Pana-
sonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M) in parallel
with 47 μF ceramic capacitor (Panasonic p/n: ECJ-
5YB0J476M,
Taiyo Yuden p/n: CEJMK432BJ476MMT). Figure 19 depicts
much lower input voltage ripple when input capacitance is
increased to 450 μF (3 x 150 μF) polymer capacitors in par-
allel with 94 μF (2 x 47 μF) ceramic capacitor.
The input capacitance should be able to handle an AC ripple
current of at least:
