Product Details
The MAX77655 is a highly efficient, complete power supply for low-power, ultra-compact applications. It provides four programmable buck-boost switching regulator outputs using only one inductor. Operating from a single Li-ion battery, the MAX77655 delivers a total of 700mA output current (3.7VIN, 1.8VOUT) in less than 40mm2 solution size.
An integrated sequencer controls full startup while an I2C interface allows the MAX77655 to be dynamically configured and monitored.
This device is part of the single-inductor multiple-output (SIMO) product family.
