FUNCTION
Supply Voltage Input. Input range from +2.7V to +5.5V. Bypass with a 10μF capacitor.
Supply Bypass Pin. Internally connected to IN. Bypass with a 0.1μF capacitor. Do not connect to an
external power source other than IN.
Ground
1.25V, 1.2% Reference Output. Capable of delivering 50μA to external loads. Bypass with a 0.22μF capaci-
tor to GND.
Feedback Input
Current-Limit Select Input. Connect LIM to GND for 0.6A current limit or LIM to IN for 1.2A current limit.
Oscillator Sync and Low-Noise, Mode-Control Input.
SYNC/PWM = IN (Forced PWM Mode)
SYNC/PWM = GND (PWM/PFM Mode)
An external clock signal connected to this pin allows for LX switching synchronization.
Active-Low, Shutdown-Control Input. Reduces quiescent current to 0.1μA. In shutdown, output becomes
high impedance.
