DC-DC Converters
Miniaturized
- PC Board mounting
REGULATED
single & dual tracking outputs
• Shipped Within 3 Days
• One Year Warranty
These versatile DC-DC Converters
are ideally suited
for powering a wide variety of analog and digital circuitry,
such as op amps, logic and microprocessors. They may
be mounted directly on a printed circuit board for OEM
applications, or installed in a socket for developmental
and small quantity requirements. For DC-DC Converters
with screw terminals, see page 18.
SPECIFICATIONS
Input Voltage:
Nominal voltage ±10%.
Input Reflected Ripple:
1% E
in
(max.)
Output Regulation:
Line:
±0.02%
Load:
±0.05%
Output Ripple
(@ 25 MHz bandwidth):
1 mV rms, 50 mV p-p (5-15V outputs).
1.5 mV rms, 75 mV p-p (18-28V outputs).
Output Voltage Setting:
Outputs are factory preset to
within ±1% of the nominal output voltage.
T/C terminal:
For single output models, the T/C terminal
can be used to trim the output more precisely to the
nominal voltage rating by connecting an external resistor
from the T/C terminal to either the + or– terminal. For dual
output models, the T/C terminal is the output common.
Polarity:
The output of single output models may be
connected in either polarity. Dual output models have a
positive/common/negative output terminal configuration.
Transient Response (NL-FL):
50 microseconds.
Overload/Short Circuit Protection:
Electronic current
limiting with automatic recovery. Models in case size ELC-
10 also have thermal protection with automatic reset.
Input/Output Isolation:
Voltage:
500 Vdc
Resistance:
100 megohms
Capacitance:
100 pF
Switching Frequency:
20 kHz minimum.
Temperature Coefficient:
0.02%/°C (Typical).
Ambient Operating Temperature:
–20 to +71°C.
Storage Temperature:
– 40 to +85°C.
Humidity:
20% to 80% R.H. (non-condensing).
Mounting:
May be mounted on printed circuit board or in
socket (see page 11).
Efficiency is in the order of 65%, and is maintained down
to low levels of output current. Input reflected ripple is
reduced to less than 1% by means of a standard
built-in pi filter, and electrostatic shielding on all six sides
minimizes radiated energy. High input/output isolation
permits separation of the output from the dc input bus to
minimize circuit interaction due to ground loops, and the
use of inputs in either polarity.
