The FAN2013 is a high-efficiency, low-noise synchro-
nous 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 volt-
age 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 com-
