The IQ24280HEC14 InQor
™
Exa converter is an iso-
lated, fixed switching frequency DC-DC converter that
uses synchronous rectification to achieve extremely high
efficiency and power density. The 24 Vin modules fea-
ture 2,250 Vdc isolation and low common mode noise.
The Exa series converters offer industry leading useable
output power for any standard “half-brick” module.
RoHS compliant (see last page).
Operational
Features
• Ultra-high efficiency, 93% at full rated load current,
95% at half rated load current
• Delivers up to 14 A of output current (392 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 resis-
tors required
• Wide output voltage trim range (-50% to +20%), see
trim section

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 haz-
ardous 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
