NAME
QFN-6 TSOT23-5
This is the enable terminal of the device. Pulling this terminal to low forces the device
EN 4 3 I into shutdown mode. Pulling this terminal to high enables the device. This terminal must
be terminated.
Feedback terminal for the internal regulation loop. Connect the external resistor divider
FB 3 4 I to this terminal. In the fixed-output-voltage option, connect this terminal directly to the
output capacitor.
GND 6 2 — GND supply terminal
This terminal is only available as an QFN package option. MODE terminal = high forces
the device to operate in the fixed-frequency PWM mode. MODE terminal = low enables
MODE 2 — I
the power-save mode with automatic transition from PFM mode to fixed-frequency PWM
mode.
This is the switch terminal and is connected to the internal MOSFET switches. Connect
SW 1 5 O
the external inductor between this terminal and the output capacitor.
