EVL3437-J-00A

EVL3437-J-00A is a MP3437 high efficiency, fully-integrated synchronous boost converter EV board (MP3437 IC available in TSOT23-8 package). The MP3437 is a 600KHz, fixed frequency, highly integrated boost converter with a wide input range. It starts from an input voltage as low as 2.7V, and supports up to 20W of peak load power from a single-cell battery. The MP3437 adopts constant-off-time (COT) control topology to provide fast transient response. The cycle-by-cycle current limit on the low-side MOSFET (LS-FET) prevents current runaway, and the high-side MOSFET (HS-FET) eliminates the need for an external Schottky diode. The integrated LS-FET and HS-FET simplify the design and save BOM cost. The MP3437 supports auto pass-through mode when VIN exceeds VOUT-SET. It also features a configurable input under-voltage lockout (UVLO) threshold and over-temperature protection (OTP). Typical applications include notebooks, AI speakers, Bluetooth speakers and portable POS systems.
