LNK60x operating frequency

When i design with PIXls Designer software, sometimes the software asks me to increase operating frequency to above 80kHz, but in the datasheet the fosc is fixed to 66kHz, can the chip's fosc go up? thanks.
Yes. You can select the operating frequency between 45 kHz and 88 kHz and enter into the appropriate cell in PIXls spreadsheet. This is usually done by selecting the resistor divider combination on the feedback winding.
