boost LLP fault. See “Configuration 62 (Config62) – Address 94” on page 50
for configuring V
using bits BST_LLP[1:0].

LLP_TIME[2:0]
Configures boost BOP fault behavior. When bit BOP_RSTART is set to ‘1’ the
IC attempts to restart after V drops down to a nominal voltage level. It is
BST
recommended to enable bit MAX_CUR when BOP_RSTART = 1 so the sec-
ond stage can deliver full output power when a boost BOP fault is detected.
[4]
BOP_RSTART This helps quickly dissipate the energy stored in the boost output capacitor
bringing down the voltage on the capacitor.
0 = Latched fault
1 = Attempts to restart if V
equals 195V for 120V application or 392V
BST
for 230V application
