PRODUCT OVERVIEW

Packaged in 1" x 2" encapsulated modules, the TWR

22W series DC/DC converters offer three outputs

arranged as a unipolar low voltage supply and a

higher voltage

bipolar output pair. The unipolar section sup-

plies either +3.3V at 4A maximum or +5V at 3A

maximum. The bipolar outputs are either ±12Vdc

at 300mA maximum or ±15Vdc at 250mA and

are ideal for op amps, linear or analog circuits. A

single TWR converter can power applications with

combined analog and digital circuits such as a

CPU-controlled voice switch, embedded telephone

modem or analytical instruments.

The input section is fully isolated from the outputs

up to 1500Vdc minimum using Basic insulation.

Three wide input ranges are available including

10-18V (12Vdc nominal), 18-36V (24Vdc nomimal)

or 36-75V (48Vdc nominal). Peak-to-peak output

ripple/noise is typically 80-100mV at full load.

Efﬁ ciencies range up to 87%.

Isolated, High Reliability 1" x 2" DC/DC Converters

Triple Output/TWR Models

The TWR 22W series outputs will limit their current

if driven to overload and may be short circuited

indeﬁ nitely without damage. The inputs will shut

down if input voltage is either over or under limits

or has reversed input voltage. These converters

will operate at higher temperatures with adequate

airﬂ ow.

The unipolar output features line and load regula-

tion of ±1%. Excellent dynamic response assures

transient load change settling within 100 microsec-

onds. Other convenience features include a remote

On/Off control to turn the outputs on via digital

logic, CPU bit, control transistor or a relay.

Fabrication uses DATEL’s advanced surface

mount automated pick-and-place assembly and

computer-controlled parameter testing. All TWR

22W series are certiﬁ ed to safety requirements in

UL, EN60950-1 and CSA-C22.2 No.60950-1, 2nd

Edition.
