FAN2013 2A Low-Voltage Current-Mode Synchronous PWM Buck Regulator November 2006 FAN2013 2A Low-Voltage Current-Mode Synchronous PWM Buck Regulator Features ■ 95% Efficiency, Synchronous Operation ■ Adjustable Output Voltage from 0.8V to VIN ■ 4.5V to 5.5V Input Voltage Range ■ Up to 2A Output Current ■ Fixed-Frequency 1.3MHz PWM Operation ■ 100% Duty Cycle, Low-Dropout Operation ■ Soft-Start Function ■ Excellent Load Transient Response ■ Power-Good Flag ■ Over-Voltage, Under-Voltage Lockout, Short-Circuit, Description The FAN2013 is a high-efficiency, low-noise synchronous PWM current mode DC-DC converter designed for low-voltage applications. It provides up to 2A continuous load current from the 4.5V to 5.5V input. The output voltage is adjustable over a wide range of 0.8V to VIN by means of an external voltage divider. The FAN2013 is enabled when the input voltage on the VIN pin exceeds the UVLO threshold. A current-mode control loop with a fast transient response ensures excellent line and load regulation. The fixed 1.3MHz switching frequency enables designers to choose a small, inexpensive external inductor and capacitor. Filtering can be accomplished with small components, reducing space and cost. and Thermal Shutdown Protections ■ 3x3mm 6-lead MLP Package Applications ■ Hard Disk Drive ■ Set-Top Box ■ Point-of-Load Power ■ Notebook Computer ■ Communications Equipment Protection features include input under-voltage lockout, short-circuit protection, and thermal shutdown.
