■ TYPICAL APPLICATION CIRCUIT
●Standard Circuit
External components:
CIN = 1μF (ceramic capacitor)
C1 = C2 = 1μF (ceramic capacitor)*
* With the custom 35kHz frequency, C1 = C2 = 3.3 μF
■ NOTES ON USE
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.
3. In order to reduce impedance between the IC's input pin and the power supply, we recommend that a capacitor (CIN)
be connected to the input side.
4. If an external power supply is applied to the output pin in order to have VOUT connected to GND during standby,
large current flows through the IC are a possibility. Further, do not use a capacitor at C2 that has a large
capacitance value.
