Characteristic Curves
Output vs. Temperature
180W convection cooled and 275W continuous with 200 LFM airflow. Derate output power to 50% at 70C.
Efficiency vs. Loading
The high efficiency is achieved by using LLC technology, PFC topology minimizing switching losses. Synchronous SCHOTTKY or ultra-fast diode is
used as rectifier in MINT1175 family because of high output voltage level.
Ripple & Noise
To verify that the output ripple and noise does not exceed the level specified in the product specification. Measured using a scope probe socket with
0.1µF ceramic and a 10µF electrolytic capacitor connected in parallel across it, BW limit with 20MHz.

Output Transient Response
50% load step within the regulation limits of minimum and maximum load, dI/dt< 0.2A/μSec. Recovery time not specified as there is no laps in regulation
with a 50% Load Step. Maximum voltage deviation is 3%.
