Typical Application Circuit
Low Voltage 0.5x Regulated Step Down Charge Pump
VPA1000
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).
