The MAX77726/MAX77727 provides POWER SUPPLIES supply solutions for ultra-low power applications where size and efficiency are critical. It features 4.6A INDUCTORS peak current protection and can deliver output currents up to 3A.
The MAX77726's output voltage can be logically set to one of four specific output voltages via the VSEL pin. Intuitive control is possible through the setting of the physical enable and mode pins.
The output voltage of the MAX77727 can be programmed via I2C. Mode switching is also possible and can be selected via the I2C interface and status readout.
The converter operates seamlessly at a minimum SWITCHES frequency of 33kHz (typical value), preventing acoustic noise interference during light load operation.
The ultrasonic mode is selected by setting the MODE pin or the MODE register.
