Description
The MPQ3431A is a 450kHz, fixed-frequency, highly integrated boost converter with a wide input range. The MPQ3431A starts from an input voltage as low as 2.7V and supports up to 20W of load power from a single-cell battery with integrated low RDS(ON) power MOSFETs.
The MPQ3431A adopts constant-off-time (COT) control topology, which provides 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.
Full protection features include programmable input under-voltage lockout (UVLO) and over-temperature protection (OTP).
The MPQ3431A is available in a QFN-13 (3mmx4mm) package.
