DESCRIPTION
NAME
NO.
FB
C1
I
Output feedback sense input. Connect FB to the converter
’s output.
VIN
A2
I
Power supply input.
This is the switch pin of the converter and is connected to the drain of the internal Power

shutdown mode. Pulling this pin to VI enables the device. This pin must not be left floating and
must be terminated.
This is the mode selection pin of the device. This pin must not be left floating and must be
terminated.
MODE = LOW: The device is operating in regulated frequency pulse width modulation mode
MODE
A1
I
(PWM) at high-load currents and in pulse frequency modulation mode (PFM) at light load
currents.
MODE = HIGH: Low-noise mode enabled, regulated frequency PWM operation forced.
GND
C2
Ground pin.
