TIMING CHART

(1)Soft-start Time

In the case of starting this IC with CE, the operation can be as in the timing chart below. When the voltage of

CE pin is beyond the threshold level, the operation of the IC starts. The threshold voltage of CE pin is in

between CE “H” input voltage and CE “L” input voltage described in the electrical characteristics table.

Soft-start circuit operates, and after the certain time, the reference voltage inside the IC is rising gradually

up to the constant value. Soft-start time is the time interval from CE starting point to the reference voltage

level reaching point up to this constant level. Soft start time is not always equal to the turn-on speed of

DC/DC converter. The power supply capacity for this IC, load current, inductance and capacitance values

affect the turn-on speed.

Depending on Power supply, Load Current, External Components

In the case of starting with power supply, when the input voltage for V is larger than UVLO released

voltage, soft start circuit operates, and after that, the same explanation above is applied to the operation.

Turn-on speed is affected by next conditions;

(1) V Voltage rising speed depending on the power supplier to the IC and input capacitor C .

(2) Output Capacitor C

value and load current value.
