decreases very
slowly due to the low initial V
OUT
. The A8436 internal timer
(Timer mode) sets a maximum timeframe of 18
μ
s for the off-
time as long as the SW node voltage is greater than 1.2 V. When
the off-time passes 18
μ
s, the internal MOSFET switch is turned
on, initiating the next charging cycle .
Input Current Limiting
The peak input current, I
SWLIM
, can be set to three levels by
configuring the ILIM pin:

Lower input current offers the advantage of a longer battery
lifetime. For faster charging time, however, use the highest
current limit.
I
SWLIM
may be adjusted during charging. Figure 5 shows a
waveform of I

is
lowered from 1.4 to 1.2 A, and charging slows slightly at the
lower current level.
