This next-generation SIMO PMIC offers three single-inductor outputs with 91 percent efficiency, which is 16 percent higher than traditional four-chip systems. With its reduced solution size, system designers can pack more functionality into their applications, such as handhelds, portable devices, and other compact consumer devices, compared to using traditional power solutions. The MAX77654 builds upon Maxim Integrated's robust portfolio of SIMIC PMICs.
As designers continue their quest to reduce form factors for compact consumer devices, they must also consider extending battery life (or reducing battery volume), as well as reducing heat dissipation and noise. The PMIC MAX77654 SIMO addresses space-constrained challenges for system designers by replacing three boost converters and three inductors with a single converter and a single inductor. It also replaces two LDOs/charge switches, a battery charger, and additional passive components, resulting in a 50 percent smaller solution. The MAX77654 enhances the end-user experience with 20 percent longer battery life by delivering 91 percent efficiency. With less than 500 nA of turn-off current and a low supply current of 6 µA with five regulators operating, designers can add more features to their ultra-low-power consumer devices. The MAX77654 produces lower heat dissipation and reduces system board temperature by more than 20 degrees Celsius compared to an alternative single-inductor system power supply solution. Furthermore, this SIMO PMIC provides superior output voltage ripple performance of less than 20 mVp-p for noise-sensitive channels.
Key Advantages
- Smaller Solution Size: The highly integrated three-output boost converter offers a 19 mm² solution size, which is 50 percent smaller than traditional discrete solutions. It consists of a SIMO PMIC, nine capacitors, and one inductor.
- Longer Battery Life: With 91 percent efficiency, a 500 nA turn-off current, and a 6 µA supply current, this solution provides 20 percent longer battery life and seven times less heat dissipation compared to discrete solutions.
- Cost-Effective Solution: It offers up to 40 percent fewer components and a 23 percent lower bill of materials cost compared to discrete solutions.
