H48SA28016NYH Datasheet, PDF (7/13 Pages) Delta Electronics, Inc. – Delphi Series H48SA, 450W Half Brick Family DC/DC Power Modules: 48V in, 28V/16A out

ELECTRICAL CHARACTERISTICS CURVES
Figure 13: Test set-up diagram showing measurement points
for Input Terminal Ripple Current and Input Reflected Ripple
Current.
Note: Measured input reflected-ripple current with a simulated
source Inductance (L_TEST) of 12 μH. Capacitor Cs offset
possible battery impedance. Measure current as shown above.
Figure 14: Output voltage ripple at nominal input voltage and
rated load current (100mV/div). Load capacitance: 330uF
aluminum, 1μF ceramic capacitor and 10μFlow ESR capacitor.
Bandwidth: 20 MHz. Scope measurement 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.
