The MAX77642/MAX77643 provide power supply solutions for low-power applications where size and efficiency are critical. The IC features a 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 load switches to manage power consumption by disconnecting external blocks when not required.

The MAX77642's 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.

This MAX77643's 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.
