Hi Juha,

Hi Juha,

The DA9062 has an internal oscillator of 6 MHz; this is divided down to a 3 MHz switching frequency for the Bucks. The Buck switching frequency can be adjusted by adjusting the OSC_FRQ register; this will alter the Oscillator frequency in steps of 1.33% with a range of ± 10 %. The GUI allows for range from -10.65 % (-8 steps) to +9.33 % (+7 steps).

Kind Regards,

Elliott Dexter
