DC-DC Converter
The IQ24500HEx08 InQor^™ Exa converter is an
isolated, fixed switching frequency DC-DC converter
that uses synchronous rectification to achieve extremely
high efficiency and power density. The 24 Vin modules
feature 2,250 Vdc isolation and low common mode
noise.The Exa series converters offer industry leading
usable output power for any standard “half-brick”
module. RoHS compliant (see last page).
Operational Features
• Ultra-high efficiency, 94% at full rated load current, 95%
at half rated load current
• Delivers up to 8 A of output current (400 W)
• Wide input voltage range: 18 – 36 V, with 50 V 100 ms
input voltage transient capability
• Fixed frequency switching provides predictable
EMI performance
• No minimum load requirement means no preload
resistors required
• Wide output voltage trim range (-50% to +10%)
Mechanical Features
• Industry standard half-brick pin-out configuration
• Brick size: 2.39" x 2.49" (63.1 x 60.6 mm)
• Total height only 0.512" (13 mm)
• Total weight: 4.3 oz. (123 grams)
Control Features
• On/Off control referenced to input side
IQ24500HEC08 Module
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 damage and consequent
hazardous conditions
• Active back bias limit provides smooth startup with
external load induced pre-bias
• Latching output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Safety Features
• 2250 V, 30 MΩ input-to-output isolation
• UL 60950-1:2003, basic insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• CE Marked
• RoHS compliant (see Page 12)
