PRODUCTION DATA
When the device is disabled through EN, the device enables the output voltage discharge mode. This mode forces both high-side and low-side MOSFETs to latch off, but turns on the internal discharge MOSFET, which is connected from SW to PGND, to discharge the output voltage. After the FB voltage drops below 50mV, the discharge MOSFET and the internal VCC LDO is turned off.
When the EN pin goes low to disable the converter and while the VCC voltage is sufficient to turn on the discharge switch, the output voltage discharge mode is activated.
