Nine-channel power management IC with advanced system safety monitoring

The SWx_RUN_MODE[1:0] bits are provided to change the mode of operation of the SWx regulator during the

RUN state. If the SWx is enabled in the Power-up sequence, the SWx_RUN_MODE[1:0] will be set to PWM by

default.

The SWx_STBY_MODE[1:0] bits are provided to change the mode of operation of the SWx regulator during the

STANDBY state.

Table 132. Mode selection in STANDBY

The default value for the SWx_STBY_MODE[1:0] bits is loaded at power-up from the OTP_SWx_STBY_EN bit.

Table 133. Default SWx mode selection in STANDBY

When the SWx regulator changes the mode between the PWM and PFM, The SWx_MODE_I interrupt will be

generated when the mode transition is finished. The INTB pin will be asserted if the SWx_MODE interrupt is not

masked.

The SWx_ILIM[1:0] bits are provided to program the current limit detection in the SWx regulator. The default

current limit is loaded at power up from the OTP_SWx_ILIM[1:0] bits.

The SWx_PH[2:0] bits are provided to control the phase shift of the switching frequency. The default switching

phase is loaded at power up from the OTP_SWx_PH[2:0] bits.
