Switching frequency is pin-selectable between 1 MHz and 2.5 MHz, letting the designer trade inductor size against ripple and efficiency.
At 300 mA output, the power dissipation is modest, but the small footprint means the copper area under the device sets the effective thermal resistance.
The switching frequency is pin-selectable to either 1 MHz or 2.5 MHz.
