Notes 1. Be sure to use the product within the Power dissipation.

2. For TA ≥ 25°C, the total loss is derated at TJ MAX = 125°C and –6 mW/°C.

(See the PT-TA characteristic curve.)

3. For TA ≥ 25°C, the total loss is derated at TJ MAX = 125°C and –4.4 mW/°C.

(See the PT-TA characteristic curve.)

4. This is an external voltage that can be applied to the output pin without deteriorating the quality of the

product or causing damage to the product.

Be sure to use the product within the rated value under any conditions where coils are inserted or power

is turned on or off. The output voltage that can be obtained during normal operation is within the output

saturation voltage range.

Note 5.

This parameter defines the voltage that can be applied when a PWM mode application circuit is

configured by applying an external voltage to the control pin. Usually, a capacitance of 0.01 µF is

connected as shown in the application circuit.
