The MAX77640/MAX77641 are a low-IQ power solution for applications where size and efficiency are critical. The device integrates a 3-output single-inductor multiple-output (SIMO) buck-boost regulator, a 150mA LDO, and a 3-channel current-sink driver. The SIMO operates on an input between 2.7V and 5.5V. The outputs are independently programmable between 0.8V .
