Low IQ SIMO PMIC with 4-Outputs Delivering up to 700mA Total Output Current

20% Smaller and 15% Less in BOM Content



The MAX77655 provides a highly-integrated power supply solution for low-power applications where size and efficiency are critical. Also, it features a single-inductor, multiple-output (SIMO) buck-boost regulator that provides four independently programmable power rails from a single inductor to minimize total solution size. The PMIC is capable of delivering a total of 700mA output current (3.7VIN, 1.8VOUT).

A bidirectional I2C 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 when the devices are on. Numerous factory programmable options allow the device to be tailored for many applications, enabling faster time to market.
