Analog Devices Inc. MAX77655 Low IQ SIMO PMIC

Analog Devices MAX77655 Low IQ SIMO PMIC is a highly-integrated power supply solution for low-power applications. The MAX77655 features a single-inductor, multiple-output (SIMO) buck-boost regulator. This 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 (3.7V_IN, 1.8V_OUT).

A bidirectional I²C interface allows for configuring and checking the device status. 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.

The Analog Devices MAX77655 PMIC is offered in a compact 3.95mm x 3.95mm WLP16 package, ideal for space-constrained applications.
