Overview of UCC28781QRTWRQ1

A key feature of the UCC28781-Q1 is its programmable adaptive burst mode (ABM), offering flexibility in managing standby mode transitions to optimize power consumption in light and no-load conditions. ABM also plays a crucial role in reducing ripple effects and minimizing audible noise, enhancing the overall user experience. Furthermore, this controller comes equipped with multiple protection modes that trigger automatic restart (retry) responses, ensuring robust operational reliability in diverse scenarios
