MAX15569
2-Phase/1-Phase QuickTune-PWM Controller with
Serial I²C Interface
Slew-Rate Configuration (0x06h)
The content of the SRREG register determines the slew
rate at both initial startup and dynamic output-voltage
transition. There are 52 possibilities of selectable slew
rates (4.5mV/µs to 44mV/µs) that cover the initial startup
(soft-start) and dynamic output-voltage transition with
different slew rates in one setting. See Table 8 for bit
descriptions and Table 9 for slew-rate selections.
