Function
Power Ground. Bypass with a 10μF ceramic
capacitor to PVIN
Inductor Connection. Connect an inductor Between
SW and the regulator output.
Analog Ground, Connect to PGND
Feedback Input. Connect an external resistor divider
from the output to FB and GND to set the output to a
voltage between 0.6V and VIN
Enable pin for the IC. Drive this pin to high to enable
the part, low to disable.
When forced high, the device operates in fixed
frequency PWM mode. When forced low, it enables
the Power Save Mode with automatic transition from
PFM mode to fixed frequency PWM mode. This pin
must be terminated.
Analog Power. Short externally to PVIN
Supply Voltage. Bypass with a 10μF ceramic
capacitor to PGND
