8.3.1.2 Fault Auto-Retry

When the TMR pin open or a capacitor is connected to primary side ground, the device auto-retries when a fault is present. The capacitor size connected to the pin determines the retry time (TRETRY). The device continues to auto-retry until the fault is cleared, at which point it resumes normal operation.
