Application Information
Layout Consideration
The PCB layout should be carefully performed to maxi-
mize thermal dissipation and to minimize voltage drop,
droop and EMI. The following guidelines must be
considered:
1. Please place the input capacitors near the VIN pin as
close as possible.
2. Output decoupling capacitors for load must be placed
near the load as close as possible for decoupling high
frequency ripples.
3. Locate APL3526/B and output capacitors near the load
to reduce parasitic resistance and inductance for excel-
lent load transient performance.
4. The negative pins of the input and output capacitors
and the GND pin must be connected to the ground plane
of the load.
5. Keep VIN and VOUT traces as wide and short as
possible.
