PMIC halves size while extending battery life for wearables
The MAX77654 SIMO PMIC replaces 3 buck-boost converters and 3 inductors with a single converter and a single inductor. It also replaces 2 LDOs/load-switches, a battery charger and passives to provide a 50% smaller solution. The greater efficiency of the solution brings a 20% longer battery life. The 500nA shutdown current and 6µA supply current with 5 regulators operating, allows more functions to be added to low-power devices. Better efficiency also yields lower heat dissipation, reducing system board temperature by over 20 degrees Celsius compared to an alternative single inductor system power solution. The SIMO PMIC also provides output voltage ripple of under 20mVp-p.
