PIN FUNCTIONS  
PIN  
DESCRIPTION  
I/O  
NAME  
VIN  
NO.  
3
I
The input supply pin for the IC. Connect VIN to a supply voltage between 2.9V and 18V. It is acceptable for  
the voltage on the pin to be different from the boost power stage input for applications requiring voltage  
beyond VIN range.  
SW  
FB  
1,2  
9
I
I
This is the switching node of the IC. Connect SW to the switched side of the inductor.  
Feedback pin for positive voltage regulation. Connect to the center tap of a resistor divider to program the  
output voltage.  
EN  
4
8
I
Enable pin. When the voltage of this pin falls below the enable threshold for more than 10ms, the IC turns  
off.  
COMP  
SS  
O
O
O
Output of the internal transconductance error amplifier. An external RC network is connected to this pin to  
compensate the regulator.  
5
Soft start programming pin. A capacitor between the SS pin and GND pin programs soft start timing. See  
application section for information on how to size the SS capacitor.  
FREQ  
10  
Switch frequency program pin. An external resistor is connected to this pin to set switch frequency. See  
application section for information on how to size the FREQ resistor.  
AGND  
PGND  
SYNC

I
I
I
Signal ground of the IC  
Power ground of the IC. It is connected to the source of the PWM switch.  
Switch frequency synchronous pin. Customers can use an external signal to set the IC switch frequency  
between 200-kHz and 2.2-MHz. If not used, this pin should be tied to AGND as short as possbile to avoid  
noise coupling.  
NC  
11  
I
Reserved pin. Must connect this pin to ground.  
Thermal Pad  
The thermal pad should be soldered to the analog ground. If possible, use thermal via to connect to top and  
internal ground plane layers for ideal power dissipation.
