Description
The MPQ9840 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution that achieves 3.5A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range. The switching frequency can be programmed or synchronized to an external clock in the range of 350kHz to 2.5MHz. The synchronous operation and ultra-low 14μA sleep mode quiescent current provide high efficiency over the output current load range, allowing the MPQ9840 to be used in a variety of step-down applications in automotive input environments and battery-powered applications.
Peak-current-mode operation provides fast transient response and eases loop stabilization. The excellent low dropout performance allows the MPQ9840 to be used in high duty cycle applications.
Full protection features include over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown. An open-drain power good (PG) signal indicates when the output is within 10% of its nominal voltage.
The MPQ9840 is available in a space-saving QFN-16 (3mmx4mm) package.

APPLICATION
TRACTION INVERTER SYSTEMAPPLICATIONAn engine roaring is becoming a sound of the past, as the adoption of electric vehicles (EVs) continues to grow at an exponential rate. Soon the only sound will be the whirring an EV motor as the traction inverter delivers power from the battery. Traction inverters are instrumental in converting energy from the high-voltage battery (400V/800V) into three-phase AC energy to drive the vehicle’s moto...

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...
