Small regulator increases efficiency for asset tracking
Maxim Integrated has added the Continua MAX38889 2.5 to 5.5V, 3A reversible buck/boost regulator to its Continua family of back up regulators. According to Maxim, system architects seeking back up power using super capacitor or other energy sources can capitalise on the high efficiency and small size of the Continua MAX38889. It is claimed to deliver the industry’s tightest output regulation of 2.5 per cent to support critical applications that demand high accuracy.
The MAX38889 features 94 per cent peak efficiency, nine per cent higher than the closest competing solution, says Maxim. This allows it to support longer back up time. It is also one third the size for integration into space constrained designs.
In applications such as smart utility meters or automotive dashboard cameras, the MAX38889 Continua regulator operates in buck mode to charge a back up power source, such as a super capacitor. When there is no mains power, the regulator reverses direction automatically, boosting the super capacitor voltage to power the system, until mains power is restored
At 218mm2, the MAX38889 is 64 per cent smaller than the closest competitor, which measures 606mm², allowing designers to reduce component count, cut board space and save bill of materials (BoM) cost. Smaller size also makes it easier to integrate into new and existing designs with tight space constraints. The MAX38889 regulates back up power for both portable and non-portable applications, such as retail price scanners and surveillance cameras, and others used in home, building, automotive, industrial automation and healthcare IoT.
Maxim Integrated also offers the MAX38889EVKIT# evaluation kit.
