PRODUCTION DATA
If the UVLO pin voltage is greater than the enable threshold and below the UVLO threshold for longer than 1.5 μs, the device is in standby mode with the VCC regulator operational, RT regulator operational, SS pin grounded, and no switching at the GATE output. The PGOOD is activated when the VCC voltage is greater than the VCC UV threshold.
