[1]

PWM selection is only available during the monitored STANDBY state. The regulator will operate in PFM when the device is in the LP_STANDBY state.

The default value for the SW1_STBY_MODE[1:0] bits is loaded at power-up from the OTP_SW1_STBY_EN bit.

Table 117. Default SW1 mode selection during STANDBY

When the SW1 regulator changes the mode between the PWM and PFM, The SW1_MODE_I interrupt will be

generated when the mode transition is finished. The INTB pin will be asserted if the SW1_MODE interrupt is not

masked.

The SW1_ILIM[1:0] bits are provided to program the current limit detection in the SW1 regulator. The default

current limit is loaded at power up from the OTP_SW1_ILIM[1:0] bits.

The SW1_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_SW1_PH[2:0] bits.

13.2.2.1 3.3 V load switch operation

The load switch operation in SW1 is provided to support systems operating from a 3.3 V input supply requiring

a 3.3 V gated output capable of being sequenced in the right order during the Power-up sequence. In such
