2) Multi-mode operation for highest overall efficiency
3) +-4% typical output voltage regulation
4) No external compensation components required
5) Complies with CEC/EPA no load power consumption and average efficiency regulations
6) Built-in output constant-current control with foldback
7) Low start-up current (8uA typical)
8) Built-in soft start
9) Built-in short circuit protection
10) AC line under/overvoltage and output overvoltage protection
11) Fixed 40kHz switching frequency
Advantages of Digital PWM Control:
1. Best solution for lowest cost, highest efficiency and small size.
2. Allows cycle by cycle signal analysis and processing.
3. Enables best in class primary feedback regulation.
4. Adapts in real time.Automatically increases controller gain when transient detected,
and automatically decreases controller gain at light load.
5. Identifies faults and reacts appropriately.
6. Enables low cost solutions, and reduces BOM by eliminating secondary feedback
components.
