PRODUCTION DATA
If the converter is disabled because of protection or fault (short-circuit protection, thermal shutdown, overvoltage protection, or undervoltage lockout), the output power FETs are set to high-impedance mode, and the output pulldown resistor is enabled (if enabled with BUCKx_RDIS_EN and BOOST_RDIS_EN bits). The turnoff time of the output voltage is defined by the output capacitance, load current, and the resistance of the integrated pulldown resistor. The pulldown resistors are active as long as the VANA voltage is above the 1.2-V level (approximately).
