PS3120A - Low noise switched capacitor voltage doubler

Description

The PS3120A is a low noise switched capacitor voltage doubler.

It produces a regulated output voltage from a 2.7V to 4.5V input.

Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the PS3120A ideally suited for small, battery-powered applications.

Features

  • Fixed 4.94V±3% Output.
  • VIN Range: 2.7V to 4.5V.
  • Output Current: Up to 110mA (VIN≥3V) Up to 230mA (VIN≥3.6V).
  • Low Noise Constant Frequency (360kHz) Operation.
  • Shutdown Current.

    PULAN TECHNOLOGY CO., LIMITED Description The PS3120A is a low noise switched capacitor voltage doubler. It produces a regulated output voltage from a 2.7V to 4.5V input. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the PS3120A ideally suited for small, battery-powered applications. The PS3120A have thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to <1μA. The PS3120A is available in the industry standard SOT-23-6L power packages. Typical Application PS3120A Features  Fixed 4.94V±3% Output  VIN Range: 2.7V to 4.5V  Output Current: Up to 110mA (VIN≥3V) Up to 230mA (VIN≥3.
