MAX77658 Ultra-Low Power PMICs Analog Devices MAX77658 Ultra-Low Power PMICs allow highly-integrated battery charging and power supply solutions for low-power applications where size and efficiency are critical. The MAX77658 offers a SIMO buck-boost regulator with three highly efficient and independently programmable power rails from a single inductor to minimize the total solution size. Furthermore, two 150mA LDOs deliver ripple rejection for audio and other noise-sensitive applications. The LDOs can also be configured as load switches to manage power consumption by disconnecting external blocks when not required.
