Output and Input Capacitor Selection
Low ESR (equivalent series resistance) capacitors should
be used to minimize the output voltage ripple. Multilayer
ceramic capacitors are an excellent choice as they have
extremely low ESR and are available in small footprints.
A 4.7糉 to 10糉 output capacitor is suf cient for most
boost applications. Larger values up to 22糉 may be used
to obtain extremely low output voltage ripple and improve
transient response. X5R and X7R dielectric materials are
preferred for their ability to maintain capacitance over
wide voltage and temperature ranges. Y5V types should
not be used.
The internal loop compensation of the LTC3537 is designed
to be stable with a minimum output capacitor value of
4.7糉 when in PWM mode on the boost regulator and
1糉 or greater on the LDO regulator. Although ceramic
capacitors are recommended, low ESR tantalum capaci-
tors may be used as well. For the LDO, see Figures 2 and
3 for output capacitor value and ESR requirements. To
reduce Burst Mode boost output voltage ripple, 10糉 is
recommended.
