rents are supplied by Cout only, and connections be-
tween Cout and the load must be short, wide copper
areas to minimize inductance and resistance.
5) The SC1109 is best placed over a quiet ground
plane area, avoid pulse currents in the Cin, Q1, Q2
loop flowing in this area. GND should be returned to
the ground plane close to the package and close to
the ground side of (one of) the output capacitor(s). If
this is not possible, the GND pin may be connected to
the ground path between the Output Capacitor(s) and
the Cin, Q1, Q2 loop. Under no circumstances should
GND be returned to a ground inside the Cin, Q1, Q2
loop.
6) BST for the SC1109 should be supplied from the
12V supply, the BST pin should be decoupled directly
to GND by a 0.1
μ
F ceramic capacitor, trace lengths
should be as short as possible. If a 12V supply is not
available, a classical boot strap method could be im-
plemented to achieve the upper Mosfet’s gate drive.
7) The Phase connection should be short .
8) Ideally, the grounds for the two LDO sections
should be returned to the ground side of (one of) the
output capacitor(s).
