300 mA output, 1 MHz or 2.5 MHz switching
The switching frequency is pin-selectable between 1 MHz and 2.5 MHz — the higher setting keeps the fundamental switching noise above the AM broadcast band and shrinks the inductor to a 0603 or 0805 footprint.
SOT-583 package and layout notes
Housed in a SOT-583 package (1.6 mm × 1.6 mm, 0.5 mm pitch), the part is a surface-mount device. The small footprint demands a controlled reflow profile — the datasheet's recommended land pattern and stencil aperture are the starting point for the PCB layout. The synchronous rectifier is integrated, so no external Schottky diode is needed.
