H24SN28012NRFA Datasheet, PDF (5/13 Pages) Delta Electronics, Inc. – Delphi Series H24SN, 350W Half Brick Family DC/DC Power Modules: 18~36Vin, 28V/12.5A out

ELECTRICAL CHARACTERISTICS CURVES
Figure 7: Output voltage response to step-change in load
current (75%-50% of Io, max; di/dt = 1A/µs). Load cap: 330µF
aluminum ,10uF Low ESR capacitor and 1µF ceramic
capacitor. Top Trace: Vout (100mV/div), Bottom Trace: Iout
(1A/div). 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.

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.
