This family of triple output DC/DC converters was developed for xDSL line card
applications. Two independently regulated converters in a 2" x 2" x 0.5" plastic
package offer 3.3V @ 4.25A and ± 12V @ ±625mA or ± 15V @ ±500mA. Unlike
topologies that provide auxiliary bipolar secondary voltages, the TWR-3.3/4250-
12/625 and TWR-3.3/4250-15/500 have fully regulated bipolar control loops that
offer the same ±1% load regulation seen on the 3.3V primary output.
Available with input ranges of 18 to 36V (-D24), or 36 to 75V (-D48), this TWR
series offers 87% efciency, ±1% line regulation, input overvoltage and undervoltage
shutdown circuitry, output overvoltage and short circuit protection, as well as current
limiting protection and thermal shutdown. The standard on/off control function can
be substituted with a sync option for multiple converter applications.
TWR triple output converters will deliver full output power in ambient,
still air environments ranging from –40 to +65°C. Designed using Basic Insula-
tion transformer construction, this family of converters guarantees 1500Vdc of
isolation voltage and meets IEC950, UL1950 and EN6950 safety standards.
"D48" models are CE marked (meet LVD requirements); CB reports are avail-
able upon request.
