Monolithic Power Systems (MPS) MPQ3431A-AEC1 Synchronous Boost Converters

Monolithic Power Systems (MPS) MPQ3431A-AEC1 Synchronous Boost Converters are 450kHz, fixed-frequency, highly integrated boost converters with a wide 2.7V to 13V start-up voltage. The MPQ3431A supports up to 20W of load power from a single-cell battery with integrated low RDS(ON) power MOSFETs.

The MPS MPQ3431A-AEC1 Synchronous Boost Converters utilize a constant-off-time (COT) control topology, which provides a fast transient response. The MODE pin allows the user to select pulse-skip mode (PSM), forced continuous conduction mode (FCCM), or ultrasonic mode (USM) under light-load conditions. The configurable input current limit provides accurate overload protection. The low-side MOSFET limits the cycle-by-cycle inductor peak current, and the high-side MOSFET eliminates the requirement for an external Schottky diode.

The Converters provide full protection features that include programmable input under-voltage lockout (UVLO) and overtemperature protection (OTP). The MPQ3431A is housed in a QFN-13 (3mm x 4mm) package.
