... DC-DC converter designed for low-voltage applications. It provides 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 FAN2013B is enabled when the input voltage on the V pin exceeds the UVLO threshold current-mode control loop with a fast transient response ensures excellent line and load regulation ...

... The internal voltage reference, V reset until V reaches the UVLO threshold. IN The FAN2013B has an internal soft-start circuit that limits the inrush current during start-up. This prevents possible voltage drops of the input voltage and eliminates the output voltage overshoot. The soft-start is implemented as a digital circuit, increasing the switch current in four steps to the P-channel current limit. Typical start-up time for a 40µ ...

... Inductor Selection The inductor parameters directly related to device performance are saturation current and DC resistance. The FAN2013B operates with a typical inductor value of 2.2µH. The lower the DC resistance, the higher the efficiency. For saturation current, the inductor should be rated higher than the maximum load current, plus half of ...
