The RT5739 is a step-down switching buck converter that can deliver the
|
|
programmable output voltage from 300mV to 1300mV with wide input voltage
|
|
supply of 2.5V to 5.5V. It can provide up to 3.5A continuous current
|
|
capability at over 80% high efficiency.

If property is present, use the 'VSEL1' register group for buck control.
|
|
Else, use the 'VSEL0' register group. This depends on external hardware

'VSEL' pin connection.
