Low quiescent current (IQ)

Your power design requires efficiency across the entire load range to extend battery life. Our low IQ boost devices minimize the amount of current draw out of the battery at ultra-light loads or even when the devices are not switching.

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.

Achieve Low EMI with Dual Random Spread Spectrum
Learn about TI's new dual random spread spectrum, or DRSS, and how it optimizes EMI reduction in multiple CISPR-25 frequency bands. This is followed by a demonstration of the level of reduction achieved with this technology.
