SNVS533C – SEPTEMBER 2007 – REVISED MAY 2013
The series combination of RC and CC1 introduces a pole-zero pair according to the following equations:
(9)
In addition, CC2 introduces a pole according to the following equation:
(10)
Where RO is the output impedance of the error amplifier, approximately 1 MΩ, and amplifier voltage gain is
typically 200 V/V depending on temperature and VIN.
Refer to Table 4 for suggested soft start capacitor and compensation components.

LAYOUT CONSIDERATIONS AND THERMAL MANAGEMENT
Figure 28. Evaluation Board Layout
High frequency switching regulators require very careful layout of components in order to get stable operation
and low noise. All components must be as close as possible to the LM4510 device. Refer to Figure 28 as an
example. Some additional guidelines to be observed:
1. CIN must be placed close to the device and connected directly from VIN to PGND pins. This reduces copper
trace resistance, which affects the input voltage ripple of the device. For additional input voltage filtering,
typically a 0.1 uF bypass capacitor can be placed between VIN and AGND. This bypass capacitor should be
placed near the device closer than CIN.
2. COUT must also be placed close to the device and connected directly from VOUT to PGND pins. Any copper
trace connections for the COUT capacitor can increase the series resistance, which directly affects output
voltage ripple and makes noise during output voltage sensing.
