The MAX77646/MAX77647 provides power supply solutions for low-power applications where size and efficiency are critical. The IC features a Single Inductor Multiple Output (SIMO) buck-boost regulator that provides three independently programmable power rails from a single inductor to minimize total solution size. A 150mA 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.
The MAX77646/MAX77647 operates with battery voltages from 1.8V with coin-cell, dual silver oxide, dual alkaline, and LiSOCL2 primary batteries.
The MAX77646 (RSEL variant) SIMO and LDO output voltages are individually programmable through resistors. A peak current limit input is used to set both the inductor's peak current limits of the device with a single resistor. Individual enable pins combined with the flexible resistor programmability allows the device to be tailored for many applications.
The MAX77647 (I2C variant) SIMO and LDO output voltages are individually programmable through I2C and in addition, includes two GPIOs with alternate modes for scalability. A bidirectional I2C serial interface allows for configuring and checking the status of the devices. An internal on/off controller provides a controlled startup sequence for the regulators and provides supervisory functionality while they are on. Numerous factory programmable options allow the device to be tailored for many applications, enabling faster time to market.
