JAJSE60B November 2017 – September 2019 ISOW7821
To design with this device, use the parameters listed in Table 4.
|Input voltage||3 V to 5.5 V|
|Decoupling capacitor between VCC and GND1||0.1 µF to 10 µF|
|Decoupling capacitor between VISO and GND2||0.1 µF to 10 µF|
Because of very-high current flowing through the ISOW7821 VCC and VISO supplies, higher decoupling capacitors typically provide better noise and ripple performance. Although a 10-µF capacitor is adequate, higher decoupling capacitors (such as 47 µF) on both the VCC and VISO pins to the respective grounds are strongly recommended to achieve the best performance. Optional 100 µF decoupling capacitor can be added between VCC and GND1 pins; refer to Power Supply Recommendations for more details.
