Integrated dc/dc converter for core processor applications in portable electronics
1 min read
ON Semiconductor is targeting the growing need for higher power densities in portable consumer electronics designs with the introduction of the NCP6338, a configurable, 6A step down dc/dc converter ic.
The NCP6338 has a programmable output voltage range from 0.6 to 1.4V in 6.25mV increments while operating down to an input voltage of 2.3V. Using a modular output strength drive combined with automatic pulse width modulation (PWM) and pulse frequency modulation (PFM), the device can adapt its efficiency performance to the load profile and thus save battery life.
"All the functionality integrated into the NCP6338 eliminates the need for additional power components that would normally be required, thereby reducing the overall bill of materials, conserving board space and simplifying the design process," commented Thibault Kassir, director of ON Semiconductor's interface and power ic products.
"The NCP6338 configures its output voltage for the actual load thereby optimising efficiency to ensure battery power is not needlessly wasted," he added. "And, by meeting the latest load transient requirements for multi core application processors this converter enables smartphones to match portable game consoles in performance and graphics quality."
The NCP6338 is offered in a 2.06 x 2.46 x 0.6mm CSP-30 RoHS compliant package.
