Down to 1.6V Input; Simpliп¬Ѓes Design
of 2-Cell NiCd/NiMH Supplies by Gregg Castellucci Features
Soft Start
To reduce inrush currents at startup, the LTC3409 offers a soft start
function, which linearly ramps up
the output voltage in about 1ms. For
instance, the average output current
required during soft start to charge a
10ВµF output capacitor to 1.8V in 1ms
is 18mA. The total output current is the
sum of the output capacitor charging
current and the current delivered to
the load as VOUT ramps up. 80 3.1VIN 70 100 2.5VIN 60
