General Description
The MAX77675 is a highly efficient, complete power supply
for low-power, ultra-compact applications. It provides
four programmable buck-boost switching outputs using
only one inductor. Operating from a single lithium-ion or Liion
battery, the MAX77675 delivers a total of 700mA output
current (3.7VIN, 1.8VOUT) in less than 40mm2 solution
size.
An integrated sequencer controls full startup while an I2C
interface allows the MAX77675 to be dynamically configured
and monitored.
This device is part of the single-inductor multiple-output
(SIMO) product family.
