Description
1
RUN
Shutdown input. When connected to a low level (lower than 0.4V) the device stops working.
When high (higher than 1.3V) the device is enabled.
2
COMP
Error amplifier output. A compensation network has to be connected to this pin. Usually a
220pF capacitor is enough to guarantee the loop stability.
3
VFB
Error amplifier inverting input. The output voltage can be adjusted from 0.6V up to the input
voltage by connecting this pin to an external resistor divider.
4
GND
Ground.
5
LX
Switch output node. This pin is internally connected to the drain of the internal switches.
6
VCC
Input voltage. The start up input voltage is 2.2V (typ) while the operating input voltage range is
from 2V to 5.5V. An internal UVLO circuit realizes a 100mV (typ.) hysteresis.
