A7566
Key Features
- step-up DC/DC converters delivering high
- efficiency in a 6- lead SOT package. Capable of
- supplying 3.3V at 100mA from a single AA cell input, the device contain an internal NMOS switch and PMOS synchronous rectifier. A switching
- frequency of 1.2MHz minimizes solution footprint
- by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM
- design is internally compensated, reducing
- external parts count. The A7566 features
- continuous switching at light loads. The device
- features low shutdown current of under 1uA.
- High Efficiency: Up to 92% 1.2MHz Constant Switching Frequency 3.3V Output Voltage at IOUT=100mA from a Single AA Cell; 5.0V Output Voltage at IOUT=500mA from one Li battery. Start-up Voltage: 0.85V (typical) Integrated main switch and synchronous rectifier. No Schottky Diode Required 2.5V to 5V Output Voltage Range Automatic Pulse Skipping Mode Operation Tiny External Components <1μA Shutdown Current Available in SOT-26 Package The A7566 is available in SOT-26 package.
