PRODUCTION DATA.
For the positive boost regulator (DCDC1) a 10-μF capacitor can be used as the input capacitor value; two 4.7-μF capacitors are used as output capacitors to reduce ESR along with a 2.2-μH inductor. For the inverting buck-boost regulator (DCDC2), a 10-μF capacitor can be used at the input capacitor value; two 4.7-μF capacitors are used as output capacitors to reduce ESR along with a 4.7-μH inductor. The charge pump pins VDDH_D and VEE_D require 100-nF capacitors to ground for reliable operation. An ESR capacitor with a value of 20 mΩ is expected for all capacitors, and ceramic X5R material or better is recommended. These values are the typical the values used; additional inductor and capacitor values can be used for improved functionality; however, the components should be rated the same as the recommended external components listed in Table 21.
