AC-MAXIM-MAX77650
Maxim-logoNextArticle
The MAX77650 and MAX77651 feature single inductor multiple output (SIMO) buck-boost regulators that provide three independently programmable power rails from a single inductor, 150mA LDO, and three current sink drivers to reduce overall component count and maximize available board space. For desigexibility, the MAX77650 operates up to 3.3V and the  MAX77651 operates up to 5V—both include an analog multiplexer (MUX) output for safe battery monitoring, making them ideal for low power designs.
