Applications requiring maximum output current especially
those at high input voltage may require application derating
at elevated temperatures.
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 LMZ14201 will properly start up into a pre-biased output.
This startup situation is common in multiple rail logic applica-
tions where current paths may exist between different power
rails during the startup sequence. The following scope cap-
ture shows proper behavior during this event.
