he SC10A series of cost
sensitive single and dual output
10 watt DC/DC converters are
specifically designed for critical appli-
cations requiring a compact, low profile
case.
These high performance 10 watt
converters offer a high switching
frequency topology, 1500 Vdc isolation,
and efficiences to 85%.
Eighteen models available: three input
voltage ranges of 9-18 Vdc, 18-36 Vdc,
and 36-75 Vdc provide regulated
outputs of 3.3, 5, 12, 15 and ±12 and
±15 Vdc.

NOTES:
1. Ripple measured with a 3.3 mf tantalum capacitor
across each output.
2. Minimum load 10% of full load. Load regulation
from full load to minimum load.
3. The SC10A series requires an external filter
capacitor across the input valued at 2.2µF @
100Vdc such as ITW/Paktron part# 225k100RA4 or
equiv.
4. Case connected to pin #1 on -48 models. Case
connected to pin #2 on -12 and -24 models
