Features
Description
!
Low noise outputs, 70 mV P-P maximum
!
Very low reflected ripple, 50 mA P-P maximum
!
Excellent regulation from no load to full load 0.2%
maximum
The low voltage FW single output converters are designed for
ultra wide input range, low noise industrial and instrument
applications requiring low input operating voltages. The wide
input range (3:1) is ideal for battery or unregulated input
applications.
!
Excellent line regulation, 0.1% maximum
!
Efficiencies to 82%
!
Six-sided shielded low thermal gradient copper case
!
Five Year Warranty
These converters are state-of-the-art 100 kHz designs that
provide outstanding line and load regulation with efficiencies
approaching 82%.
The single outputs are regulated with a high loop gain
current mode control method that provides linear regulator
type performance with a true, high efficiency switching DC/DC
topology. The large amount of loop gain also insures excellent
input ripple rejection and line transient response.

Dynamic response is the peak overshoot during a transient as
defined in note 6.
(8) The input ripple rejection is specified for DC to 120 Hz ripple with
a modulation amplitude of 1% of Vin.
(9) For module protection only, see note 3.
(10) The functional temperature range is intended to give an additional
data point for use in evaluating this power supply. At the low
functional temperature the power supply will function with no
side effects, however, sustained operation at the high functional
temperature will reduce expected operational life. The data
sheet specifications are not guaranteed over the functional
temperature range.
(11) The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
All Parameters measured at Tc=25°C, nominal input voltage
and full rated load unless otherwise noted. Refer to the
CALEX Application Notes for the definition of terms,
measurement circuits and other information.
Noise is measured per CALEX Application Notes. Measurement
bandwidth is 0-20 MHz.
Determine the correct fuse size by referring to CALEX Application
Notes.
Case is tied to Pin 5, - Output.
Short term stability is specified after a 30 minute warmup at full
load, constant line and recording the drift over a 24 hour period.
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.

the CALEX Application Notes for the definition of terms,

(2) Noise is measured per CALEX Application Notes. The output
noise is measured with a 0.1µF, 50V, ceramic capacitor connected
directly across the output pins. Measurement bandwidth is 0-20
MHz.
(3) Determine the correct fuse size by calculating the maximum DC
current drain at low line input, maximum load and then adding 20
to 25% to get the desired fuse size. A slow blow type fuse
is recommended.
(4) No minimum load required.
(5) Short term stability is specified after a 30 minute warm-up at full
load, constant line and recording the drift over a 24 hour period.
(6) The transient response is specified as the time required to settle

Case is tied to Pin 5, CMN.
The functional temperature range is intended to give an additional
