Efficiency vs. Loading The high efficiency is achieved by using LLC technology, PFC topology minimizing switching losses. Synchronous SCHOTTKY or ultrafast diode is used as rectifier in CINT1175 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.1uf ceramic and a 1uF electrolysis capacitor connected in parallel across it, BW limit with 2MHz. www.slpower.com CINT1175 REV 5.4, 6 April15 7
Output Transient Response 5% load step within the regulation limits of minimum and maximum load, di/dt<.2a/µsec. Recovery time not specified as there is no laps in regulation with a 5% 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.
