Description
Setting to ‘1’ sets the AS3658 into standby mode. All
regulators defined in reg.17h “Reg Power1Ctrl” and
reg.1Eh “Reg Power2 Ctrl are disabled except those
regulators enabled by reg.81h “Reg standby mode”.

W
XRESET will be pulled to low. A normal startup of all
regulators will be done with any interrupt (has to be
enabled before entering standby mode). During this
startup, regulators defined by Reg standby mode
register are continuously on.
Divide internal clock oscillator by 2 to reduce
quiescent current for low power operation

Internal clock frequency divided by two. All
timings are increased by two. Switching

frequency of all DCDC converters are divided
by two. Reduced transient performance of
DCDC converters.
