Designed for use in battery-powered applications, the FAN5308 is a high-efficiency, low-noise synchronous PWM current mode and pulse skip (power save) mode DC-DC converter. It can provide up to 800mA of output current over a wide input range from 2.5V to 5.5V. The output voltage can be externally adjusted over a wide range of 0.8V to 5.5V by means of an external voltage divider. At moderate and light loads, pulse skipping modulation is used. Dynamic voltage positioning is applied, and the output voltage is shifted 0.8% above nominal value for increased headroom during load transients. At higher loads, the system automatically switches over to current mode PWM control, operating at 1.3 MHz. A current mode control loop with fast transient response ensures excellent line and load regulation Product Highlights: 96% Efficiency, Synchronous Operation Adjustable Output Voltage Options from 0.8V to VIN 2.5V to 5.5V Input Voltage Range Up to 800A Output Current Fixed Frequency 1.3MHz PWM Operation High Efficiency, Power Save Mode 100% Duty Cycle Low Dropout Operation Soft Start Output Over-Voltage Protection Dynamic Output Voltage Positioning 25A Quiescent Current Thermal Shutdown and Short Circuit Protection Pb-Free 3x3mm 6-Lead MLP Package
