HX4002 - Low Noise Regulated Charge Pump

General Description

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.

Key Features

  • Fixed 3.3V or 5V Outputs VIN Range: 1.8V to 4.5V(HX4002-3.3) 2.7V to 5.5V(HX4002-5) Output Current: Up to 200mA (HX4002-5) Up to 50mA (HX4002-3.3) Constant Frequency Operation at All Loads Low Noise Constant Frequency (1.2MHz) Operation Shutdown Disconnects Load from Input Shutdown Current.
