STR3A400 Series
 Improving efficiency in all load area
- For External Power supply regulation
(EU: ErP Lot 7 (Tier 2), U.S.: DoE Level VI propose)
- Green mode : Oscillation frequency decreases to reduce the switching loss
in light load
- Step drive control : VRM of secondary rectification diodes can be set to
lower value than usual → Low VF

PFC ON/OFF Circuit
Using SSC3S921(LLC) and SSC2016S(PFC)
Sanken’s PFC IC SSC2016S (P.63) has low VCC threshold voltage of 8.5V(typ.). It is lower than general PFC IC. Thus,
SSC2016S can be operated by SSC3S921 REG voltage of 10V(typ.).
By PFC ON/OFF Function of SSC3S921, The operation of SSC2016S can be stopped when SSC3S921 becomes standby
operation.
Combination of SSC3S921 and SSC2016S can achieve the following simple circuit.
 Simple circuit.
 PFC operation synchronous with the standby
operation of SSC3S921.
