Einführung
Abstract: The MAX77640/MAX77641 provide highly integrated power supply solutions for low-power applications where size and efficiency are critical. The MAX77640/MAX77641 device datasheet provides the complete hardware and electrical description for these devices. This Programmer’s Guide focuses on the register map for the devices and provides general advice for programmers.
Changing Regulator Output Voltages
The regulator output voltages are programmable. When a regulator is off, the output voltage may be directly programmed.
However, when the regulator is on and the output voltage needs to be increased or decrease program a voltage ramp from the existing voltage to the new desired voltage. Programming a ramp is
recommended for voltage increases to minimize inrush current. Programming a ramp is recommended on voltage decreases to minimize regulator undershoot when it reaches its target voltage.
