MAX77659 SIMO Power Management IC (PMIC)

Analog Devices MAX77659 SIMO Power Management IC (PMIC) is optimized for rechargeable earbuds, wearables, and other applications that emphasize low supply current and small solution size. The MAX77659 features a dual-input Single-Inductor Multiple-Output (SIMO) buck-boost regulator. The device provides one charging rail and three independently programmable power rails from a single inductor to minimize the total solution size. A 100mA LDO provides ripple rejection for audio and other noise-sensitive applications. The LDO can also be configured as a load switch to manage power consumption by disconnecting external blocks when not required. A highly configurable switching charger supports a wide range of Li+ battery capacities and includes battery temperature monitoring for additional safety (JEITA).
