next-generation, board-mountable, isolated, fixed switching

frequency dc-dc converters that use synchronous rectification

to achieve extremely high power conversion efficiency. The

power dissipated by the converter is so low that a heatsink

is not required, which saves cost, weight, height, and

application effort. All of the power and control components

are mounted to the multi-layer PCB substrate with high-yield

surface mount technology. Since the PowerQor converter has

no explicit thermal interfaces, it is extremely reliable. RoHS

Compliant (see page 15).

Protection Features

• Input under-voltage lockout disables converter at low input

voltage conditions

• Output current limit and short circuit protection protects

converter and load from permanent damage and consequent

hazardous conditions

• Active back bias limit prevents damage to converter

from external load induced pre-bias

• Output over-voltage protection protects load from

damaging voltages

• Thermal shutdown protects converter from abnormal

environmental conditions

Safety Features

Pending

• 2000V, 30MΩ input-to-output isolation provides input/output

ground separation

• UL 60950-1 recognized (US & Canada), basic insulation rating

• TUV certified to EN60950-1

• Board and plastic components meet UL94V-0

flammability requirements

Operational Features

• High efficiency, 88% at full rated load current

• Delivers up to 15A of output current with minimum derating - no

heatsink required

• Wide input voltage range: 35-75V, with 100V, 100ms input voltage

transient capability

• Fixed frequency switching provides predictable EMI performance

• No minimum load requirement means no preload resistors required

Control Features

• On/Off control referenced to input side (positive and negative logic

options are available)

• Remote sense for the output voltage compensates for output

distribution drops

• Output voltage trim permits custom voltages and voltage margining
