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 1µF or more value of capacitor between VOUT and GND, C3 as shown in typical application above. (Recommended value is from 10 µF to 22µF.) 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 VREFOUT and GND, C6 as shown in typical application of the previous page. The capacitance value of C6 is between 0.1 µF and 1.0µF. |
