STMicroelectronics STWK01
The transferred wake-up pulse is detected by the ZCD pin of the main IC that resumes the operation. The device generates a wake-up pulse also in case, during burst mode operation, it detects an overvoltage condition on the output.| Part No. | STWK01 |

DESCRIPTION
ObThe STWK01 device is intended to operate at a flyback converter output diode. When at a light load or no-load the main device STCH01 enters burst mode operation and stops switching, the wake-up controller senses at the secondary side that there is no switching activity and remains waiting that the output voltage discharges down to the threshold set by an external resistive divider connected to the sensing pin Vsns: when the internal threshold is reached, the wake-up controller switches on the internal MOSFET for a short time...
