PRODUCT PREVIEW Information. Product in design phase of development. Subject to change or discontinuance without notice.
The output voltage of the regulator can be changed by writing to the BUCKx_VOUT register. The voltage change for buck regulator is always slew-rate controlled, and the slew-rate is defined by the BUCKx_SLEW_RATE[2:0] bits in BUCKx_CTRL_2 register. During voltage change the forced PWM mode is used automatically. When the programmed output voltage is achieved, the mode becomes the one defined by load current, and the BUCKx_FPWM bit in BUCKx_CTRL_1 register.
The voltage change and Power-Good interrupts are shown in Figure 9.
