| EM600 SERIES Single and dual output * * * * * 70% efficiency typical Unregulated outputs 24 pin DIP package No derating Short circuit protection 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 -25C to +71C with no output derating. The case size is 1.25 x 0.8 x 0.4 inches.

Maximum value at full load. Figure is peak-to-peak. Line regulation is per 1.0% change in input voltage. 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. CASE F 0.08 (2.00) 0.02 Dia.
