DESCRIPTION
FEATURES
The A7801B is a low noise, constant frequency● Low Noise Constant Frequency (1MHz) (1MHz) switched capacitor voltage doubler.
● Output Current: Up to 300mA
● Output Accuracy: ±2.5% The A7801B provides regulated output voltage
● VIN Range: 2.1V to 5.0V from a 2.1V to 5.0V input with up to 230mA of
● Automatic Soft-Start Reduces Inrush Current output current. Low external parts count (one flying
● No external Inductor capacitor and two small bypass capacitors at VIN
● Shutdown Current <1uA and VOUT) make the A7801B ideally suited for small, battery-powered applications. A7801B is a new charge-pump architecture maintains constant switching frequency to zero load and reduces both output and input ripple. The A7801B have thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. Built-in soft-start circuitry prevents excessive inrush current during start-up. APPLICATION
● USB OTG
● Digital Camera
● LED Driver
● Smart Card Readers TYPICAL APPLICATION The A7801B is available in SOT-26 package.
