SY5055A Description
Features The SY5055A is a PFC+LLC bo controller, which PF>0.95, THD<5% integrates a Boost PFC controller and a resonant halfbridge controller. The Boost converter works in CrM/DCM mode to minimize switching losses and get better EMI performance. Proprietary control is adopted to get unity PF and lowest THD.
