Procedure
Example
5. Output Capacitor Selection (COUT )
A. Since the TC2575 is a forward–mode switching regulator
with voltage mode control, its open loop 2–pole–1–zero
frequency characteristic has the dominant pole–pair
determined by the output capacitor and inductor values.
For stable operation, the capacitor must satisfy the
following requirement:
COUT ≥ 7.785
VIN(max)
[
F]
VOUT x L [F]
B. Capacitor values between 10
F and 2000F will satisfy
the loop requirements for stable operation. To achieve an
acceptable output ripple voltage and transient response,
the output capacitor may need to be several times larger
than the above formula yields.
C. Due to the fact that the higher voltage electrolytic capaci-
tors generally have lower ESR (Equivalent Series
Resistance) numbers, the output capacitor’s voltage
rating should be at least 1.5 times greater than the output
voltage. For a 5.0V regulator, a rating of at least 8.0V is
appropriate, and a 10V or 16V rating is recommended.
5. Output Capacitor Selection (COUT )
