MONOLITHIC POWER SYSTEMS (MPS) MPQ3432GLE-AEC1-P DC-DC Synchronous Boost Regulator, Adjustable, 0.8V to 13V in, 0.8V to16V/21A out, WFQFN-13

MPQ3432 is 600KHz, fixed-frequency, highly integrated boost converter with a wide input range. The MPQ3432 starts up from an input voltage (VIN) 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 MPQ3432 adopts constant-off-time (COT) control to provide 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 need 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.
