Isolation DC-DC Converter
The InQor® quarter-brick converter series is composed of
next-generation, board-mountable, isolated, fixed switching
frequency dc-dc converters that use synchronous rectification
to achieve extremely high power conversion efficiency. Each
module is supplied completely encased to provide protection
from the harsh environments seen in many industrial and
transportation applications.
Operational Features

• Delivers full power with minimal derating - no heatsink required
• Operating input voltage range:
9-36 V, 40 V transient for 100 ms
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Size: 1.54" x 2.39" x 0.50"
(39.0 x 60.6 x 12.7mm)
• Total weight: 3 oz (85 g)
Protection Features
• Input under-voltage lockout
• Output current limit and short circuit protection
• Active back bias limit
• Output over-voltage protection
• Thermal shutdown
Control Features
• On/Off control referenced to input side
• Remote sense for the output voltage
• Output voltage trim range of -20%, +10%
Safety Features
• 2250 V, 30 MW input-to-output isolation
• UL/cUL 60950-1 recognized (US & Canada), basic insulation
rating
• TUV certified to EN60950-1
• Meets 72/23/EEC and 93/68/EEC directives which facilitates
CE Marking in user’s end product
• Board and plastic components meet UL94V-0 standard
• RoHS compliant (see Page 28)
