DC/DC Conver

ter

• Ultra-high efficiency, 95% at full rated load current

• Delivers up to 400 Watts of output power with minimal

derating - optional open frame unit available

• Input voltage range: 38V – 55V, with 80V for 100ms

input transient capability

• Fixed frequency switching provides predictable EMI per-

formance

• On-board input and output filtering

Operational Features

Operational Features

• Industry standard half-brick pin-out configuration

• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)

• Total height only 0.50” (12.7mm) for baseplated unit,

open-frame only 0.420” (10.67mm)

• Total weight: 4.3 oz. (123 grams) for baseplated unit,

open-frame 2.6oz. (75 grams)

Mechanical Features

Mechanical 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

Contr

ol 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

• Active back bias limit prevents damage to converter

from external load induced pre-bias

• Latching output over-voltage protection

• Thermal shutdown

Pr

otection Features
