NXP Semiconductor’s new PCA9410 and PCA9410A are highly efficient 3MHz step-up (boost) DC-DC converters. They convert input voltages ranging between 2.5V and 5.25V to a fixed output voltage of 5.0V. The output current limit is 500mA.
These 1.2mm x 1.2mm devices are optimised for battery-powered applications: high conversion efficiency of up to 94% helps to provide for extended battery life in any portable product design.
In addition, the devices’ switching frequency of 3MHz enables the use of a small inductor with a value of 1μH or less. The PCA9410 devices offer tightly controlled regulation, providing output voltage accuracy of ±2% at nominal and static conditions. Even over the full current, voltage and temperature range, the output is accurate to within ±3%. The PCA9410 totally disconnects the input from the output when disabled. The PCA9410A connects the input to the output when disabled.
