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. 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.
