A7506

AiT Semiconductor Inc. www.ait-ic.com A7506 600mA, 1.2MHz CONSTANT FREQUENCY SYNCHRONUS STEP-UP DC-DC CONVERTER DESCRIPTION FEATURES The A7506 is synchronous, fixed frequency, step-up High Efficiency: Up to 92% DC/DC converters delivering high efficiency in a 1.2MHz Constant Switching Frequency 6-lead SOT package. Capable of supplying 3.3V at 3.3V Output Voltage at IOUT=100mA from a Single 100mA from a single AA cell input, the device AA Cell; 5.0V Output Voltage at IOUT=500mA from contain an internal NMOS switch and PMOS one Li battery. synchronous rectifier. A switching frequency of Low Start-up Voltage: 0.85V 1.2MHz minimizes solution footprint by allowing the Integrated main switch and synchronous rectifier. use of tiny, low profile inductors and ceramic No Schottky Diode Required capacitors. The current mode PWM design is 2.5V to 5V Output Voltage Range internally compensated, reducing external parts Automatic Pulse Skipping Mode Operation count. The A7506 features continuous switching at Tiny External Components light loads. Anti-ringing control circuitry reduces EMI <1µA Shutdown Current concerns by damping the inductor in discontinuous Anti-ringing Control Reduces EMI mode, and the device features low shutdown current Available in SOT-26 Package. of under 1A. The A7506 is available in SOT-26 Package. APPLICATION Cellular and Smart Phones ORDER INFORMATION Microprocessors and DSP Core Supplies Wireless and DSL Modems Package Type Pa...
