3DAW_3 Series
3W - Single/Dual Output - Wide Input - Isolated & Regulated
DC-DC Converter
DC-DC Converter
3 Watt
Wide 2:1 Input voltage range
High efficiency up to 86%
Isolation voltage 3kVDC
Operating Temperature
Range: -40°C to +85°C
EN60950 approval
The 3DAW_3 series are isolated 3W DC-DC products with 2:1 input
voltage and conventional voltage output. The product has a relatively
compact DIP package and features high efficiency, operating tempera-
ture of -40°C ~+85°C, remote control and continuous short-circuit
protection.
Short circuit protection (SCP)
The smaller size and fine cost design make the converter an ideal so-
lution in communication, instruments, and industrial electronics ap-
plications.
