EV3437-RP-00A

EV3437-RP-00A is an MP3437 high-efficiency, fully-integrated synchronous boost converter EV board (MP3437 IC available in QFN-10 package). It is a 600KHz fixed frequency, wide input range, highly integrated boost converter. It starts from an input voltage as low as 2.7V, and supports up to 20W load power from 1-cell battery. MP3437 adopts constant-off-time (COT) control topology providing fast transient response. QFN package has MODE pin which can support mode selection of PSM, FCCM and USM in light load condition. And the integrated low-side and high-side MOSFET simplify the design and save BOM cost. The MP3437 supports auto-pass-through mode when VIN is higher than VOUT-SET in PSM mode. It also features with programmable input undervoltage lockout (UVLO) and over temperature protection. Typical applications include notebook, AI speaker, Bluetooth speaker and portable POS system.
