AXP223 comes with 5 synchronous step-down DC-DCs, 14 LDOs,2 switch as well as multiple timing and controlling methods.
The work frequency of DC-DC is 3MHz by default, which is adjustable via registers. External small inductors and capacitors can
be connected as well. In addition, 5 DC-DCs can be set in PWM mode or auto mode (automatically switchable according to
the AXP223 load). See register REG80H.

DCDC1/2/3/4/5
DCDC1 output voltage ranges from 1.6 V to 3.4V，
DCDC2/4 output voltage ranges from 0.6 V to 1.54V
DCDC3 output voltage ranges from 0.6 V to 1.86V
DCDC5 output voltage ranges from 1.0 V to 2.55V
Can be programmed via registers
DCDC5 Voltage setting depends on DC5SET pin Voltage：

DCDC output capacitor is recommended to use small ESR ceramic capacitors above 10uF X7R；recommend 1.5uH
inductors，Besides, the inductor saturation current should be larger than 50% of the largest demanded current in power
circuitry.
