VPA1000 Datasheet (Renesas) - Step Down Charge Pump

VPA1000, Step Down Charge Pump

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
