Power trends

Power density

We know you need more power in a smaller form factor. Our boost regulators harness multiple leading power technologies for the most power dense, size-optimized and best thermal performance solutions. Our ultra-efficient controllers and integrated converters can help you meet any design goal.

Featured products for power density
TPS61178 ACTIVE 20-V, 10-A fully integrated sync boost with load disconnect
TPS81256 ACTIVE Integrated Power Solution, 3W High-Efficiency boost converter module in MicroSiP™ package
TPS61088 ACTIVE 10-A Fully-Integrated Synchronous Boost Converter

Mitigating boost regulator EMI is a major challenge for many power supply designs. Our devices and EMI mitigation designs are validated for required IEC and CISPR standards to minimize EMI, output ripple and audible noise when using a DC/DC switcher. Our industry-leading, dual, random spread-spectrum technology mitigates EMI by spreading energy in multiple bands of interest using two random frequency generators.
