• Manufacturer Part Number: RT9703CS
• Description: 80m?, 3A Smart Universal Power Switch with Flag
• Manufacturer: RICHTEK [Richtek Technology Corporation]

Fault Flag Filtering (Optional)
The transient inrush current to downstream capacitance
may cause a short-duration error flag, which may cause
erroneous over-current reporting. A simple 1ms RC low-
pass filter (10k
short-duration transients.
PCB Layout
In order to meet the voltage drop, droop, and EMI
requirements, careful PCB layout is necessary. The
following guidelines must be considered:
Keep all input and output traces as short as possible
and use at least 150-mil, 2 ounce copper for all races.
Avoid vias as much as possible. If vias are necessary,
make them as large as feasible.
Place a ground plane under all circuitry to lower both
resistance and inductance and improve DC and transient
performance (Use a separate ground and power plans
if possible).
Locate the bypass capacitors as close as possible to
the input and output pin of the RT9703.
