Introduction

AI Translation

The SY5055A is a PFC+LLC combo controller; it integrates a Boost PFC controller and a resonant halfbridge LLC controller. The Boost converter works in CrM/DCM mode to minimize switching losses and get better EMI performance. Average current control is adopted to get unity PF and the lowest THD. Burst function increases efficiency at low load. Reliable input BO/BI protection, Boost output OVP/UVP, over current protection, Boost feedback protection guarantees safety work. The LLC converter adopts integrated current mode control to get fast dynamic response and easy loop compensation parameters design, also peripheral capacitor sense circuit is eliminated. In contrast to traditional LLC control scheme, the SY5055A shows a high efficiency at low load due to DCM mode. This mode operates in the power region between CCM mode and Burst mode. Four level Burst point can be set simply and Burst period can be well regulated. Within the whole load range, from full load to no load, high efficiency and low audio noise can be achieved.
