DESCRIPTION
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
