... Most of the heat loss that occurs in the BD00IC0WEFJ is generated from the output Pch FET. Power loss is determined by the total VCC-VO voltage and output current. Be sure to confirm the system input and output voltage and the output current conditions in relation to the heat dissipation characteristics of the VCC and VO in the design. Bearing in mind that heat dissipation may vary substantially depending on the substrate employed (due to the power package incorporated in the BD00IC0WEFJ make certain to factor conditions such as substrate size into the thermal design ...

... BD00IC0WEFJ ●About Input-to-output capacitor It is recommended that a capacitor is placed nearby pin between Input pin and GND, output pin and GND. A capacitor, between input pin and GND, is valid when the power supply impedance is high or drawing is long. Also as for a capacitor, between output pin and GND, the greater the capacity, more sustainable the line regulation and it makes improvement of characteristics by load change ...

... BD00IC0WEFJ (11) Testing on application boards When testing the application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. Always discharge capacitors after each process or step. Always turn the IC’s power supply off before connecting removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic measure ...
