Typical Application Circuit
Figure 1 Typical Application Circuit
Pin Description
No. Name
Description
1 NC No Connection.
2
FB
Feedback Pin. The output voltage is feedback to this pin. Generally this pin is
connected to the external resistor divider to sense the output voltage.
3
COMP
Compensation Pin. Connect the compensation network between COMP pin and
GND.
4 NC No Connection.
Shutdown Input Pin. Pulling this pin high, places the part into a shutdown mode.
5
SHDN
Shutdown mode is characterized by a very low quiescent current. In shutdown mode,
all the functionality of all blocks is disabled and the on-chip 5V regulator is also
shutdown. Pulling this pin low places the part into normal operation mode.
6
VIN
Input Supply Voltage. Positive terminal of input supply. The input voltage range is
4.5V to 32V. Connect a local bypass capacitor from this pin to GND.
5V Regulator output. A bypass capacitor of 4.7uF should be connected from this pin
7
VCC
to GND. If the input voltage is less than 5.5V, the voltage at VCC pin may be less
than 5V.
8
DRV
Gate Drive Pin. Gate drive for the external N-channel MOSFET. Connect this pin to
the gate of external N-channel MOSFET.
9
GND
Ground. Negative terminal of input supply.
10
CS
Inductor Current Sense Pin. The inductor current is sensed at CS pin on the
cycle-by-cycle basis for both the current mode control and over current protection.
