HX4002 Datasheet (Hexin Semiconductor) - Low Noise Regulated Charge Pump

HX4002, Low Noise Regulated Charge Pump

The HX4002 is a low noise, constant frequency (1.2MHz) switched capacitor voltage doublers.

The HX3200-3.3can produce a regulated output voltage of 3.3Vfrom a minimum input voltage of 1.8V (2 alkaline cells)whereas the HX3200-5 can produce 5V from a minimum of 2.7V (Li-Ion battery) input.
