ADP1823
Rev. A | Page 30 of 32
The ADP1823 can also be configured to drive an output load of
less than 1 A. Figure 34 shows a typical application circuit that
drives a 1.5 A and a 3 A loads in an all multilayer ceramic
capacitor (MLCC) solutions. Notice that the two MOSFETs
used in this example are dual-channel MOSFETs in a
PowerPAK® SO-8 package, which reduces cost and saves layout
space. An alternative to using the dual-channel SO-8 package is
using two single MOSFETs in SOT-23 or TSOP-6 packages,
which are low cost and small in size. For input voltages less than
3.7 V, it is recommended to use MOSFETs that are fully turned
on at VGS less than 3 V. Because there is a forward voltage (VF)
drop across the Schottky diode D1 or D2, for input voltages less
than 3.3 V, the effective voltage to the internal gate drivers may
not be enough to drive a large load at the output. A Schottky
diode with VF less than 0.5 V at IF of 100 mA is recommended
for input voltages less than 3.3 V.
