... IN The BD95513MUV controls the duty cycle and output voltage based upon the input voltage at this pin, so voltage variations or oscillations on this line can cause operation to become unstable. This pin also acts as the voltage input for the switching block, so insufficient coupling impedance can also cause operation to become unstable. Therefore, this line should be bypassed with either a power capacitor or RC filter. ・ ...

... BD95513MUV ●Operation The BD95513MUV is a switching regulator incorporating ROHM’s proprietary H When V drops suddenly due to changes in load, the system quickly restores the output voltage by extending the t OUT interval. This improves the regulator’s transient response. When light-load mode is activated, the IC employs the Simple ...

... BD95513MUV (11) Regarding IC input pins This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. PN junctions are formed at the intersection of these P layers with the N layers of other elements, creating parasitic diodes and/or transistors. For example (refer to the figure below): When GND > ...
