Output Capacitor
The effective series resistance of the output capacitor
directly affects the amplitude of the output voltage ripple.
(The product of the peak inductor current and the ESR
determines output ripple amplitude.) Therefore, a capacitor
with the lowest possible ESR should be selected. Smaller
capacitors are acceptable for light loads or in applications
where ripple is not a concern. The Sprague 595D series of
tantalum capacitors are amongst the smallest of all low ESR
surface mount capacitors available. Table 1 lists suggested
component numbers and manufacturers.
Board Layout Guidelines
As with all inductive switching regulators, the TC115
generates fast switching waveforms which radiate noise.
Interconnecting lead lengths should be minimized to keep
stray capacitance, trace resistance and radiated noise as
low as possible. In addition, the GND pin, input bypass
capacitor and output filter capacitor ground leads should be
connected to a single point. The input capacitor should be
placed as close to power and ground pins of the TC115 as
possible.
