The FAN2013 is a high-efficiency, low-noise, synchronous Pulse Width Modulated PWM currentmode 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 by means of an external voltage divider.

The FAN2013 is enabled when the input voltage on the VIN pin exceed 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. Softstart limits inrush current during start-up conditions.

The device is available in a 3x3mm 6-lead MLP.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
