Description
The MINT1175 Series models provide the highest power density for a power supply in a 2” x 4” size. Ideal for use in
Home Healthcare and Portable Medical Device Applications and more. With input & output monitoring alarms plus
isolated 12V/0.4A fan, it is one the most feature rich supplies and can easily fit in 1U chassis. Exceeding the medical
device strict requirements, the MINT1175 has the lowest earth leakage current with less than 200µA, satisfies 2MOPP
reinforced isolation requirements of IEC60601-1 3rd edition, and can be purchased as Class I or II configurations.

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.
Noise & Ripple
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%, This test is performed on the MAIN OUTPUT ONLY.
Output Overload Characteristic
Supply shall protect itself against Overload conditions. The Power Supply shall recover from Overload Conditions without operator intervention.
Output Overshoot
When supply is turned on, off or when the load is stepped 100%, the Power Supply Overshoot/Undershoot shall not exceed minimum or maximum of
output voltage regulation.
