The CXUS65138 is a Micro-Power switched capacitor voltage converter that delivers a regulated output. No external inductor is required for operation.
The CXUS65138 can deliver up to 100mA 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 CXUS65138 uses a pulse skipping technique to provide a regulated output from a varying input supply. The CXUS65138 contains a thermal management circuit to protect the device under continuous output short-circuit conditions.
