Shutdown. When SHDN is pulled low, the MAX17030/MAX17036
immediately pull PWRGD low, CLKEN becomes high impedance, all
enabled phases are activated, and the output voltage is ramped
down to 12.5mV; then DH and DL are pulled low and CSNI discharge
FET is turned on.
High X X Disabled
Fault Mode. The fault latch has been set by the MAX17030/MAX17036
UVP or thermal-shutdown protection, or by the OVP protection. The
controller remains in fault mode until V
CC power is cycled or SHDN
toggled.
