Features
| 800 V avalanche-rugged power MOSFET allowing achieving ultra wide-range input Vac |
| Embedded HV startup and sense FET |
| PWM current-mode controller |
| OCP with selectable threshold (IDlim) and 2ndOCP with higher value (IDMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode |

| Two operating frequencies: 60 kHz (L type) or 115 kHz (H type) |
| 60 kHz (L type) or 115 kHz (H type) |
| Jittered frequency reduces the EMI |
| Extra power timer (EPT) blanks the overload current for few seconds |
| Output overvoltage protection with tight tolerance and digital noise filter |
| Soft-start reduces the stress during startup and increases IC lifetime |
| Automatic restart after a fault condition |
| Thermal shutdown increases system reliability and IC lifetime |
