峰值电流检测提供逐周期过电流保护
前沿消引（LEB）避开电流上升的前沿尖峰，消除因此引起的误动作干扰
过载保护（OLP）当过载时，输出电压变低，光耦趋向开路，接在反馈脚的电容电压会上升到一个较高的值，当达到Vsd时，触发OLP
过压保护（OVP）当反馈开路或其他原因引起VCC上升到20V时产生保护
软启动（soft start）内部提供15mS软启动功能，减小电源启动时通过MOSFET的电流和电压应力
高压启动开关内部集成高压启动开关，可直接接高压，内部通过电流源向VCC电容充电，当达到启动电压后关闭，与高压断开，高压端不在提供电流，没有损耗，提高效率
间歇工作（Burst Mode）轻载时 输出电压上升 反馈脚的电压降低 降低到一定程度时开关停止 输出电压下降 反馈脚上升
到一定程度开关恢复这个过程大量地减少开关动作，减小了开关损耗
内部集成增强型650V/700V的SenseFET（比例电流感应，省却外部电流采样电阻，极大减小功耗）

How does e-SeriesII FPS operate ?
Switch is turned on at the minimum VDS(Valley voltage)Once switch is turned on, the valley voltage is ignored during the blanking time (tB) Next turn-on is prohibited during tBAfter the blanking time, the minimum VDSis detected only during the detection time window (tw)If sync doesn’t resonate within tB, the switch is forced to turn on at the end of tB(CCM operation)The switching frequency is within some range regardless of input voltage and load variationNormally the switching frequency is within extremely narrow range during the valley switching

Standard Planar MOSFET SuperFET
SuperFET
- Rdson is very low 非常低
SuperFET采用多层外延生长结构降
低漂移区的阻抗实现低的Rdson
- Qgd/Qgs 比率更低
- 更低的关断损耗
- 由于有宽的体内二极管结构，使
得 dv/dt 的承受能力更高
