Q48SA52001NNFA Datasheet, PDF (6/12 Pages) Delta Electronics, Inc. – Delphi Series Q48SA, 60W Quarter Brick Family DC/DC Power Modules: 36~75V in, 52V/1.15A out

ELECTRICAL CHARACTERISTICS CURVES
Figure 11: Input reflected ripple current, i_s, through a 12µH
source inductor at nominal input voltage and rated load current
(20 mA/div，2us/div).
Figure 12: Output voltage noise and ripple measurement test
setup.
Figure 13: Output voltage ripple at nominal input voltage and
rated load current (Io=1.15A)(50 mV/div, 2us/div)
Load capacitance: 1µF ceramic capacitor and 10µF electrolytic
capacitor. Bandwidth: 20MHz. Scope measurements should be
made using a BNC cable (length shorter than 20 inches).
Position the load between 51 mm to 76 mm (2 inches to 3
inches) from the module.
