VPA1000 General Description

The VPA1000 is a low voltage 0.5x regulated step-down charge pump. It is designed as a low cost replacement for inductor-based step-down switching regulators (buck), or a high efficiency replacement for linear regulators (LDO). At full load, it can save nearly 500mW of power compared to a standard L.
