Power trends
Power density
Your power design needs high-power outputs in small spaces with minimum heat, and our high-efficiency products allow us to address those thermal issues in space-constrained applications. Our buck-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.
Low EMI
Mitigating buck-boost regulator EMI is a major challenge for many power supply designs. Our devices and designs are validated for required CISPR performance to minimize EMI, output ripple, audible noise and other drawbacks of 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.
Low quiescent current (IQ)
Your power design requires efficiency across the entire load range to extend battery life. Our buck-boost devices get the most out of a battery by responding to draining voltage inputs and our ultra-low IQ buck-boost regulators minimize the amount of quiescent current draw at light loads or while disconnected.
