Pin Definitions
Pin #
Name
Description
A1
MODE
MODE. Logic 1 on this pin forces the IC to stay in PWM Mode. Logic 0 allows the IC to automatically
switch to PFM Mode during light loads. The regulator also synchronizes its switching frequency to
two times the frequency provided on this pin. Do not leave this pin floating.
B1
SW
Switching Node. Connect to output inductor.
C1
FB
Feedback. Connect to output voltage.
C2
GND
Ground. Power and IC ground. All signals are referenced to this pin.
B2
EN
Enable. The device is in Shutdown Mode when voltage to this pin is <0.4 V and enabled when
>1.2 V. Do not leave this pin floating.
A2
VIN
Input Voltage. Connect to input power source.
