The Supereta™ Series offers an industry
standard quarter brick high current power
module with true useable output power. Its
82% full load efficiency (85% at 75% of full
load) and superior thermal performance
make the Supereta™ Series of power
modules ideally suited for tight space and
power-hungry applications in demanding
thermal environments. This rugged building
block is designed to serve as the core of
your high reliability system. A wide output
voltage trim range, -20 to +10%, and remote
sensing are standard features enhancing
versatility.
• Latched output over-voltage protection
• Auto-recovery full protections:
o Input under and over voltage
o Output over-current
o Output short circuit
o Thermal limit
Measured at the location specified in the thermal
measurement figure. Maximum temperature varies
with model number, output current, and module
orientation – see curve in thermal performance
section of the data sheet.
