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%)
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
