Pin Functions

PIN I/O DESCRIPTION
NAME NO.
AGND 7 I Signal ground of the IC
COMP 8 O Output of the internal transconductance error amplifier. An external RC network is connected to this pin to compensate the regulator.
EN 4 I Enable pin. When the voltage of this pin falls below the enable threshold for more than 10ms, the IC turns off.
FB 9 I Feedback pin for positive voltage regulation. Connect to the center tap of a resistor divider to program the output voltage.
FREQ 10 O 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.
NC 11 I Reserved pin. Must connect this pin to ground.
PGND 12,13,14 I Power ground of the IC. It is connected to the source of the PWM switch.
SS 5 O Soft start programming pin. A capacitor between the SS pin and GND pin programs soft start timing. See Application and Implementation for information on how to size the SS capacitor.
SW 1,2 I This is the switching node of the IC. Connect SW to the switched side of the inductor.
SYNC 6 I 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 possible to avoid noise coupling.
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.
VIN 3 I The input supply pin for the IC. Connect VIN to a supply voltage between 2.9 V and 18 V. 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.
