60 / 101 page  DA9062 PMIC for Applications Requiring up to 8.5 A Datasheet Revision 3.8 15-Feb-2022 CFR0011-120-00 60 of 99 © 2022 Renesas Electronics 10 Application Information 10.1 Component Selection The following recommended components are examples selected from requirements of a typical application. The final component selection will be dependent on the specific application. The electrical characteristics (for example, supported voltage/current range) have to be cross-checked and component types may need to be adapted from the individual needs of the target circuitry. 10.1.1 Resistors Table 33: Recommended Resistors Pin Value Tol. Size (mm) Rating (mW) Part IREF 200 k Ω ±1% 1005 100 Panasonic ERJ2RKF2003x 10.1.2 Capacitors Ceramic capacitors are used as bypass capacitors at all VDD and output rails. When selecting a capacitor, especially ones with high capacitance and small size, the DC bias characteristic has to be taken into account. On the VSYS main supply rail, a minimum distributed capacitance of 40 μF (actual capacitance after voltage and temperature derating) is required. Buck input capacitors should be within 1.5 mm distance from the supply pin, and the output capacitor should be close to the inductor. Table 34: Recommended Capacitors Pin Value Tol.
