A functional description of each pin can be found in the FUNCTIONAL PIN DESCRIPTION section beginning on page 16. Pin 1 Pin Name FREQ Formal Name Oscillator Frequency Definition This switcher frequency selection pin can be adjusted by connecting external resistor RF to the FREQ pin. The default switching frequency (FREQ pin left open or tied to VDDI) is set.
