90+ SLS (SRC/ LLC + SR) CM6901/1A – – – – Smaller Transformer because the Lm is greater fsw (SLS) ~ 0.5 fsw (LLC) SLS (SRC+LLC+SR) does not need the litz wire For 300W desktop application, its Lm > 1mH with 20mS hold up time – 96 96 96 at 115Vac – Square Wave Input Harmonics helps the gains – LLC to maintain the negative feedback, Lm needs to be lower that is why LLC transformer is much bigger – FM + 2 PWMings ‧ SR Ideal Diode PWMing at LLC region (for Full Load) ‧ Light Load PWMing (For Light Load) – OVP auto restart/latch (latched when standby power is available) – CM6901 auto restart/latch (ILIMIT = 1.0V) – CM6901A both Voltage Feedback (Vfb = 2.5V) and Current Feedback (Iimit = 50mV) – Patented Technologies
