Application information
7.1
Charge pump capacitors C1 and C2
The values of charge pump capacitors C1 and C2 are critical to ensure adequate output
current and avoid excessive peak currents. It is suggested to use values in the range of 0.22
µF to 1.0 µF and avoid the use of higher values of CO capacitors, in order to obtain best
performance. Ceramic or tantalum capacitors are recommended.
7.2
Input and output capacitors C3 and C4
The type of input capacitor (C3) and output filter capacitor (C4) used is not critical, but it
does affect performance. Tantalum, ceramics or aluminium electrolytic are suggested. For
lowest ripple, use large, low effective series resistance (ESR) ceramic tantalum capacitors.
If the input supply source impedance is very low, C3 can be omitted. The typical application
circuit shows the component values for proper operation using minimal board space. The
input bypass capacitor (C3) and output filter capacitor (C4) should be at least 10 µF. Many
capacitors exhibit 40% to 50% variation over temperature. Compensate for capacitor
temperature coefficient by selecting a large nominal value to ensure proper operation over
temperature.
7.3
Layout consideration
In the below figure, the typical application evaluation board of ST619LB is reported. A good
layout ensures stability and helps maintain the output voltage under heavy loads. For best
performance, use very short connections to the capacitors.
