产品概述 返回TOP
The CXUS65139 is a switched capacitor voltage converter that delivers a regulated output. No external inductor is required for operation. CXUS65139 also integrates one 500mA load switch.
The CXUS65139 can deliver up to 500mA to the voltage regulated output. It features very low quiescent current and high efficiency over a large portion of its load range, making this device ideal for battery-powered applications. Furthermore, the combination of few external components and small package size keeps the total converter board area to a minimum in space-restricted applications.
The CXUS65139 uses charge pump technique to provide a regulated output from a varying input supply. The CXUS65139 contains a thermal management circuit to protect the device under high temperature conditions.
The CXUS65139 is available in the Green TDFN-3×3-8L package and is rated over the -40℃ to +85℃ temperature range.
