NOTES
*
All parameters measured at Tc = 25°C, 5.00V input voltage,
full rated load and a 10μF solid tantalum capacitor connected
across the input and output pins, unless otherwise noted.
Refer to the CALEX Application Notes for the definition of
terms, measurement and other information.
Noise is measured per CALEX Application Notes. Measurement
bandwidth is 20 MHz. Input Reflected Ripple and output noise
are measured with a 10μF tantalum capacitor connected across
the input and output pins.
(1)
(2)
Output Voltage Accuracy measured at 75% of maximum Rated
Load.
Load Regulations measured relative to 75% of maximum Rated
Load Current. See Output Voltage vs. Output Load Curves.
Line Regulation is for a 1.0% change in Input Voltage.
Use input fuse for protection. See Applying the Input.
The case Thermal Impedance is specified as the case
temperature rise over ambient per package watt dissipated.
Specifications subject to change without notice.

General Information
The 1 Watt SIP series provides isolated semi-regulated
outputs of 5, 6.5, 7, 12, 14, 15, 17, and 24 VDC. The high
efficiency low noise push-pull design operates at 350 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 assembled to your main PC
board.
Applying The Input
Figure 1 shows the recommended input connections for the 1
Watt Output SIP series. This series is only protected for
momentary output short circuits to common so a fast acting
fuse is recommended to protect the input circuit. It should not
be omitted as it serves to prevent unlimited current from
flowing in the case of an overcurrent at the load.
C1 may not be required when the power source is less than
2" from the unit. The source impedance should be less than
Figure 1.
1 Watt SIP Series Typical Application
0.5 ohm over the frequency range of DC to 350 kHz. A 10μF
solid tantalum capacitor will satisfy the requirements for C1,
and should be within 2" of the converter.
