DC-DC Converter
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 âhalf-brickâ 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 â 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
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
IQ24280HEC14 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 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
Safety Features
⢠2250 V, 30 MW input-to-output isolation provides
input/output ground separation
⢠UL/cUL 60950-1 recognized (US &âCanada), basic
insulation rating
⢠TUV certified to EN60950-1
⢠Meets 72/23/EEC and 93/68/EEC directives which
facilitates CE Marking in userâs end product
⢠Board and plastic components meet UL94V-0 flammabil-
ity requirements
