By use of these test circuits,the typical characteristics were obtained as shown in the following pages:

Test Circuit 1: Typical Characteristics 1) 2) 3) 4) 5) 9) 10) 13) 14) 16)

(Typical Characteristics 13) and 14) were measured by replacing the capacitor shown in

Note1 with a 1µF Capacitor)

Test Circuit 2: Typical Characteristics 11) 12)

Test Circuit 3: Typical Characteristics 7) 8)

Efficiency η is shown by the following formula:

η=(VOUT × IOUT) / (VIN × IIN)

Test Circuit 4: Typical Characteristics 6)

Test Circuit 5: Typical Characteristics 15)

Test Circuit 6: Typical Characteristics 17)

Test Circuit 7: Typical Characteristics 18)

Test Circuit 8: Typical Characteristics 19) 20)

In the present IC, input current at no load is defined as supply current.(CE=VSS).

And when CE=VDD, the input current (no load) is defired as standby current.
