VR5510 Power OFF

[ajnas-c]

Hi,

In the VR5510, after the OTP has been completed, is it possible to turn off the LDO or BUCK using MCU via I2C?

Regards.

Hi Ajnas,

OTP programming determines the power-up sequence for the regulators. When the power-up sequence is finished, the main state machine is in Normal_M mode, which is the application running mode with all the regulators on. Then all regulators can be individually disabled using corresponding bits (LDOxDIS, BUCKxDIS, BOOSTDIS, VPREDIS) in the M_REG_CTRL1 register (Table 84 in the datasheet).

Best regards,

Tomas
