■ NOTES ON USE

■ELECTRICAL CHARACTERISTICS

FOSC＝120kHz, Ta=25℃

■ TYPICAL APPLICATION CIRCUIT

●Standard Circuit

External components:

C1 = C2 = 1μF (ceramic capacitor)*

* With the custom 35kHz frequency, C1 = C2 = 3.3 μF

1. Please use the IC & external components: within the specified electrical characteristics range and ensure that

absolute maximum ratings are not exceeded.

2. For C1 & C2, please use a capacitor with as small an ESR value as possible.

be connected to the input side.

large current flows through the IC are a possibility.

Further, do not use a capacitor at C2 that has a large

capacitance value.
