AXP202 Power Output Channel Control

Manages the seven power output channels of the AXP202 PMIC: DCDC2, DCDC3, LDO2, LDO3, LDO4, LDOio (via GPIO0), and EXTEN (external enable pin). Each channel can be individually enabled/disabled and its output voltage configured.

Details

• DCDC2: 700-2275mV, 25mV steps (register 0x23)
• DCDC3: 700-3500mV, 25mV steps (register 0x27)
• LDO2: 1800-3300mV, 100mV steps (via LDO24OUT_VOL bits[3:0])
• LDO3: 700-3500mV, 25mV steps (register 0x29)
• LDO4: 1250-3300mV, fixed lookup table (21 entries)
• LDOio: 1800-3300mV, 100mV steps (register 0x91, via GPIO0)
• EXTEN: External enable pin only, no voltage control

Note

LDO4 uses a discrete lookup table. Setting a value not in the table quantizes to the nearest entry.

EXTEN is an on/off control only; setVoltage/getVoltage are not applicable.
