EM600 SERIES
Single and dual output
• 70% e fficie ncy typical
• Unre gulate d outputs
• 24 pin DIP package
• No de rating
• Short circuit prote ction
This series of low cost, unregulated DC/DC converters comes in ultra miniature
24 pin DIP packages. Five different models with a Pi network input filter that
suppresses input reflected ripple current. The units feature 5V output at 1 Watt,
and 12V, ±12V, and ±15V outputs at 1.5 Watts; input voltages are either 5V or
12V with ±10% input range. These DC/DC converters are ideal for high density
PC board applications where space is at a premium and where high efficiency is
more important than line and load regulation. Pertinent specifications include
70% efficiency, ±3% output voltage accuracy, 100mV pk-pk output ripple and
noise, and 300VDC Isolation. Switching frequency is fixed and operating
temperature range is –25°C to +71°C with no output derating. The case size is
1.25 x 0.8 x 0.4 inches.

Figure is peak-to-peak.
Line regulation is per 1.0% change in input voltage.
0.08 (2.00)
Load regulation is for load change from 100% to 20% (see graph).
Standard specifications are conservative and can be optimised for specific
applications. In particular, converter start-up at lower than specified
temperature, wider input voltage range and output voltage adjustment are
all relatively simple modifications to the standard product. Consult factory
for details.

On dual output models the four common pins are internally connected.
The outputs can be returned through one pin while the others remain
floating.
Fixed frequency design provides for easier input filtering and better noise
performance.
