MPQ3431CGLE-AEC1-Z

MPQ3431C is a 450KHz, fixed-frequency, highly integrated boost converter with a wide input voltage (VIN) range. The MPQ3431C starts from a VIN as low as 2.7V and supports up to 20W of load power from a single-cell battery with integrated, low on resistance (RDS(ON)) power MOSFETs. The MPQ3431C 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 current limit provides accurate overload protection. The low side MOSFET (LS-FET) limits the cycle-by cycle inductor peak current, and the high-side MOSFET (HS-FET) eliminates the requirement for an external schottky diode. Full protection features include configurable input under-voltage lockout (UVLO) and overtemperature protection (OTP). Applications include automotive boost, super capacitors, backup batteries.
