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.

Featured products for power density
TPS55288 ACTIVE

36V, 16A buck-boost converter with PPS control

LM5176 ACTIVE 55V wide VIN synchronous 4-switch buck-boost controller
TPS63806 ACTIVE 2.5-A high-efficient buck-boost converter with optimized load step response in tiny WCSP
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.

TPS55288 ACTIVE

36V, 16A buck-boost converter with PPS control

TPS552882 ACTIVE 36-V, 16-A buck-boost converter

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.
