FAN2013 Datasheet | Fairchild Semiconductor

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 acplished with small ponents, 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 puter - munications Equipment Protection features include input under-voltage lockout, short-circuit protection, and thermal shutdown. Soft-start .. limits in-rush current during start-up conditions. The device is available in a 3x3mm 6-lead MLP.
