General Information
The 1 Watt SLC series provides isolated, semi-regulated
outputs of ±5, 7, 12, 14, 15, and 17 VDC. The high efficiency
low noise push-pull design operates at 105 kHz which reduces
to a minimum your external filter requirements. The converter
is packaged in a non-conductive plastic case and can be
water washed after being assembled to your PC board.
Applying The Input
Figure 1 shows the recommended input connections for the
SLC Dual series. C1 may not be required when the power
source is less than 2" from the unit. The source impedance
should be less than 0.5 ohm over the frequency range of DC
to 165 kHz. A 10μF/10V solid Tantalum capacitor will satisfy
the requirements for C1, and should be placed as close to the
converter as possible.
NOTES
*
All parameters measured at Tc=25 °C case temperature,
nominal input voltage and full rated load unless otherwise
noted. Refer to the CALEX Application Notes for definition
of terms, measurement circuits and other information.
Noise is measured per CALEX Application notes. All noise
measurements are made with a 10uF/35V Tantalum capacitor
connected directly across the input and outputs. Measurement
bandwidth is 0-20 MHz.
Output voltage accuracy is measured at 75% of maximum load.
Output balance is the percent difference in voltage from the plus
to the minus output at 75% of maximum load.

(4)
Load regulation is measured relative to 75% maximum load.
Load regulation is specified with both outputs changing
simultaneously.
Cross regulation is measured relative to 75% maximum load.
Cross regulation is measured by operating the +output at 75%
of maximum load and varying the -output as specified. The
change in the +output is the cross regulation.
Line regulation is for a 1% change in the input voltage.
Current limiting must be accomplished by using a current limited
source or fuse in the input circuit.
The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
Specifications subject to change without notice.

Figure 1.
Typical input and output connections for the SLC Dual series.
C1 = 10μF if converter is more than 2" from the main power source.
C2 = 2.2μF minimum, 10 μF typical, may be spread around your board.
