Use a 1
μ
F or more capacitance value of bypass capacitor between V
IN
pin and GND, C1 as shown in the
typical application above. Connect the capacitor as short as possible to the IC.
In terms of the capacitor for setting delay time of the latch protection, C2 is shown in typical application above.
Latch delay time depends on this C2 value. Refer to the Latch Protection Operation Timing Chart.
Connect a 1
μ
F or more value of capacitor between V
OUT
and GND, C3 as shown in typical application above.
(Recommended value is from 10
μ
F to 22
μ
F.) If the operation of the composed DC/DC converter may be
unstable, use a tantalum type capacitor instead of ceramic type
Connect a capacitor between V
REFOUT
and GND, C6 as shown in typical application of the previous page.
The capacitance value of C6 is between 0.1
μ
F and 1.0
μ
F.
