ZERO COIL CURRENT DETECTION
The current of the lower (synchronous) MOSFET is monitored
by a zero coil current detection circuit which inhibits the syn-
chronous MOSFET when its current reaches zero until the
next on-time. This circuit enables the DCM operating mode,
which improves efficiency at light loads.
PRE-BIASED STARTUP
The LMZ12002EXT will properly start up into a pre-biased
output. This startup situation is common in multiple rail logic
applications where current paths may exist between different
power rails during the startup sequence. The following scope
capture shows proper behavior during this event.
