APPLICATION INFORMATION
Figure 8 shows startup waveforms of a 1.2-V V
OUT
voltage under different pre-bias scenarios. The first trace
is when the output voltage starts with zero pre鈭抌ias. The second and third traces, respectively, the pre-bias
levels are 0.5 V and 1.0 V.
VIN = 5 V
VOUT = 1.2 V
(200 mV/div)
PREBIAS = 1 V

PREBIAS = 0.5 V

Startup Waveforms
The recommended V
OUT
voltage pre-bias range is less than or equal to 90% of final regulation. That is, a
pre-bias level between 90% and 100% of final regulation could lead to sinking the pre-bias supply. If the V
OUT
voltage is initially set to higher than 100% of final regulation, the controller forces sinking current at the end of
soft-start in order to bring the output quickly into regulation.
