PRODUCTION DATA
When the device is enabled initially, the 120-μs device configuration starts if VCC is greater than VVCC-UVLO. During device configuration, the light load switching mode is selected. The device configuration is reset when the device shuts down or VCC falls down below 2.2 V. The preferred way to reconfigure the device is to shut down the device. During the configuration time, a 33-kΩ internal EN pulldown resistor is connected, the minimum sourcing capability of the VCC regulator is 100 mA and the RT pin is regulated to 0.5 V by the internal RT regulator.
