Maxim Integrated MAX77654 Ultra-Low Power PMIC provides highly-integrated battery charging and power supply solutions for low-power applications that require size and efficiency. The MAX77654 PMIC features a SIMO buck-boost regulator that provides three independently programmable power rails from a single inductor to minimize total solution size. Audio and other noise-sensitive applications implement the two 100mA LDOs, offering ripple rejection. The LDOs provide the option to be configured as load switches, managing power consumption by disconnecting external blocks when not required.
