Pin Function
Feedback. Input to the error amplifier. Connect to the external resistor divider
network to set the output voltage.
Supply Voltage (Input): Supply voltage for the internal switches and drivers.
Enable LDO Mode (Input): Logic low enables the internal LDO and disables the
PWM operation. Logic high enables the PWM mode and disables the LDO
mode.
Enable (Input). Logic low will shut down the device, reducing the quiescent
current to less than 5 µ A.
Switch Output after inductor.
Switch (Output): Internal power MOSFET output switches before Inductor
Power Ground. Requires input capacitor to GND.
Analog Supply Voltage (Input): Supply voltage for the analog control circuitry and
LDO input power. Requires bypass capacitor to GND.
LDO Output (Output): Connect to V
capacitor and should not be loaded.
Internal circuit bias supply. Must be de-coupled to signal ground with a 0.1 µ F
