TWR Series

30W, Triple Output DC/DC Converters

This family of triple output DC/DC converters was developed for

xDSL line card applications. Two independently regulated converters

in a ꢀ" x ꢀ" x 0.5" plastic package offer 3.3V @ 4.ꢀ5A and 1ꢀV @

ꢁꢀ5mA or 15V @ 500mA.

FEATURES

PRODUCT OVERVIEW

Unlike topologies that provide auxiliary bipolar

secondary voltages, the TWR-3.3/4ꢀ50-1ꢀ/ꢁꢀ5 and power in ambient, still air environments rang-

TWR-3.3/4ꢀ50-15/500 have fully regulated bipolar

control loops that offer the same 1% load regula-

tion seen on the 3.3V primary output.

TWR triple output converters will deliver full output

Independently regulated 3.3V and 1ꢀV or

15V outputs

ꢀ

ing from –40 to +ꢁ5°C. Designed using Basic

Insulation transformer construction, this family of

converters guarantees 1500Vdc of isolation voltage

and meets IEC950, UL1950 and ENꢁ0950 safety

standards. "D48" models are CE marked (meet LVD

requirements).

3.3V @ 4.ꢀ5A and 1ꢀV @ ꢁꢀ5mA

or 15V @ 500mA

ꢀ

Available with input ranges of 18 to 3ꢁV (-Dꢀ4), or

3ꢁ to 75V (-D48), this TWR series offers 87% efﬁ-

ciency, 1% line regulation, input overvoltage and

undervoltage shutdown circuitry, output overvolt-

age and short circuit protection, as well as current

limiting protection and thermal shutdown.
