0 `描述 This is a high efficiency 300-W AC/DC reference design. The design can be biased from external supply or configured for Self-Bias Auxillary mode for operation directly off the AC mains. The PFC is fully internally compensated, reducing design complexity and PCB design. Protections include 3-level OCP, line brown-out, PFC Bulk OVP plus UVP and OTP. 特性 88.9% @115V, 90.6% @230V average efficiency 83.68% @115V, 85.07% @230V 10% load efficiency High Power factor 99.5%, 6% typical THD @230Vac 50Hz Less than 200mW No-Load-Power @115Vac acheivable in Auxulliary Self-BIAS mode 397ms turn-on time Line Brownout Protection Using the UCC29950EVM-631 300-W PFCLLC Off-Line PSU Module.pdf (1.77 MB, 下载次数: 12 ) TIDA-00520 BOM.pdf (230.92 KB, 下载次数: 7 ) TIDA-00520 Schematic.pdf (260.26 KB, 下载次数: 7 ) tidc958(1).zip (327.21 KB, 下载次数: 8 ) ` 0
