AMLCD Application
Figure 3 shows a power supply for active matrix
(TFT-LCD) flat-panel displays. The positive and
negative charge pump outputs are configured
with discrete components. Adjust the output
capacitance and compensation component
values as necessary

Layout Consideration
High frequency switching regulators require very
careful layout for stable operation and low
noise. All components must be placed as close to
the IC as possible. Keep the path between the
SW pin, output diode, output capacitor and GND
pin extremely short for minimal noise and ringing.
The input capacitor must be placed close to the
IN pin for best decoupling. All feedback
components must be kept close to the FB pin to
prevent noise injection on the FB pin trace. The
ground return of the input and output capacitors
should be tied close to the GND pin. See the
MP1542 demo board layout for reference.
