Description
Selection Chart
The 24S5.2000CD DC/DC converter is designed for fast
integration with your system’s power needs. With no external
components or filtering necessary for all but the most critical
applications, these converters can provide power instantly.
This saves you costly engineering time required to design
your system around the power converter.

NOTES
AllparametersmeasuredatTc=25°C,nominalinputvoltage
and full rated load unless otherwise noted. Refer to the
CALEX Application Notes for the definition of terms,
measurement circuits and other information.
(6) The transient response is specified as the time required to settle
from a 50 to 75 % step load change (rise time of step = 2 µSec)
to a 1% error band.
*
(7) Dynamic response is the peak overshoot during a transient
as defined in note 6 above.
(2) Noise is measured per CALEX Application Notes. Measurement
bandwidth is 0-20 MHz for peak-peak measurements, 10 kHz to
1 MHz for RMS measurements. Output noise is measured with
a 0.01µF / 100V ceramic capacitor in parallel with a 1µf / 35V
Tantalum capacitor across output pins. Input reflected ripple
is measured into a 10µH source impedance.
(8) The input ripple rejection is specified for DC to 120 Hz ripple with
a modulation amplitude of 1% of Vin.
(9) Thecasethermalimpedanceisspecifiedasthecasetemperature
rise over ambient per package watt dissipated.
(10) Specifications subject to change without notice.
(3) To determine the correct fuse size, see CALEX Application
Notes.
(4) The Case is tied to the -input pin.
(5) Short term stability is specified after a 30 minute warmup at full
load, constant line and recording the drift over a 24 hour period.
