Description
The MPQ3432 is 600kHz, fixed-frequency, highly integrated boost converter with a wide input voltage (VIN) range. The MPQ3432 starts up 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.
Constant-off-time (COT) control 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 need for an external Schottky diode.
Full protection features include configurable input under-voltage lockout (UVLO) protection and over-temperature protection (OTP).
The MPQ3432 is available in a QFN-13 (3mmx4mm) package.

APPLICATION
ONBOARD CHARGING MODULE (OBCM)APPLICATIONElectric vehicles (EVs) are becoming more present every day, with the adoption of EVs growing at an exponential rate. Onboard charging (OBC) is a very important part of EVs, since it determines the maximum possible charge rate while an AC charger is connected to the vehicle. The maximum charge capability for a fully electric vehicle is typically between 6.6kW and 22kW, and for a plug-in hybrid veh...

DESIGN CONSIDERATIONS TO SUSTAIN AUTOMOTIVE CRANK CONDITIONSARTICLEModern vehicles using 12V battery systems are subjected to a number of transient conditions. Some transients involve high-voltage pulses, while others may be under low-voltage conditions. Crank transients are low-voltage conditions that occur when a car engine starts, and the car battery drops several volts below its normal operating range for a brief time. The requirements to maintain normal veh...
