FEATURES

DESCRIPTION

The NMT series is a range of DC/DC convert-

ers offering three output voltages of -24V, -48V

and -72V from a single isolated 5V or 12V input

voltage. The product is designed for use with

telecommunications circuits requiring an on board

supply for the -72V RING-TIP connection service

generated from a nominal 5V or 12V DC input

supply rail. The device also offers battery level

voltages of -24V and -48V for access control and

data pump IC’s. The product is packaged in an

8 pin SIP case for minimum PCB footprint. The

rated power may be shared or drawn from any

one output providing the total output load does not

exceed 3W.

RoHS compliant

Triple outputs (-24V, -48V & -72V)

Input/output isolation 1kVDC

Power sharing on outputs

Industrial temperature range

UL 94V-0 package material

Internal SMD construction

Toroidal magnetics

No external components required

Power density 1.65W/cm

For full details go to

1. Assuming all 3 channels are equally loaded.

2. Assuming only 1 channel is loaded.

3. Calculated using MIL-HDBK-217F with nominal input voltage at full load.

4. Supply voltage must be disconnected at the end of the short circuit duration.

SELECTION GUIDE

NMT0572SC

NMT1272SC

When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external

capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the

additional external capacitance for reliable start up.
