MP3429 is a highly integrated, wide input voltage, 600KHz fixed operating frequency boost chip.
Its minimum input voltage is as low as 2.7V.
Thanks to the built-in low-resistance power MOSFET, the output power can reach 30W when powered by a single lithium battery.
The PSM/FCCM/USM working state at low load can be selected through the mode pin.
The low-side MOSFET has cycle-by-cycle current limiting to avoid runaway current, and the high-side MOSFET no longer requires an external Schottky diode.
