Hello,
Below is a table from the LP8725 datasheet regarding dynamic voltage scaling for BUCK1.
BUCK1 may be controlled with an external pin or with a register bit, yet the table implies that BUCK1 is solely controlled by the DVS pin.
DVS1 DVS OUTPUT
Reg0x00 pin
Bit2
0 0 BUCK1_V2 Reg 0x09[4-0]
0 1 BUCK1_V1 Reg 0x08[4-0]
1 0 BUCK1_V2 Reg 0x09[4-0]
1 1 BUCK1_V1 Reg 0x08[4-0]
The pin and bit descriptions imply, to me at least, that the table should be like this
DVS1 DVS OUTPUT
Reg0x00 pin
Bit2
0 0 BUCK1_V2 Reg 0x09[4-0]
0 1 BUCK1_V1 Reg 0x08[4-0]
1 0 BUCK1_V1 Reg 0x08[4-0] <= changed this line
1 1 BUCK1_V1 Reg 0x08[4-0]
Can someone please confirm the second table is the correct operation. Otherwise, please explain how the bit controls BUCK1
Regards,
Steve
