FSL538H的20W智慧音箱电源方案

内置800V功率管，算是比较高的，性价比比较好吧！

Rugged 800V FET with 3.8 Ω Typ.RDS(on) with Built-in HV current source for start up--> Easy and Rugged design with minimal external components

Fine-tunable Skip Mode Operation
-->High Efficiency across all operating conditions

Integrated Line Compensation
-->Constant Maximum power Limitation

Line Brown-in, Brown-out Function
-->Robust design in case of poor Ac grid network

Line Over-voltage Protection (LOVP)
-->Robust design in case of poor Ac grid network

Fsw options: 100 & 130 kHz
-->Allows design trade-offs between space and efficiency

Seamless implementation of isolated and non-isolated topologies
-->Design flexibility

Peak Current: FSL538A = 860mA
-->Design versatility
