Description
The MPQ2123 is a configurable-frequency (300kHz to 2.2MHz), synchronous step-down converter. It can achieve up to 2A of continuous output current (IOUT) with peak current control for excellent transient response and efficiency. It operates from a 2.7V to 6V input voltage (VIN) range, and can generate an output voltage (VOUT) as low as 0.606V. The MPQ2123 is ideal for a wide range of applications, including automotive infotainment systems, clusters, telematics, and portable instruments.
The MPQ2123 integrates a 40mΩ high-side MOSFET (HS-FET) and a 30mΩ synchronous rectifier for high efficiency without an external Schottky diode. The MPQ2123 can be configured to operate in advanced asynchronous modulation (AAM) mode or forced continuous conduction mode (FCCM) under light-load conditions. AAM mode provides high efficiency by reducing switching losses at light loads, while FCCM offers controllable frequency and a lower output ripple.
The MPQ2123 features soft start (SS), an external sync clock, enable (EN) control, and a power good (PG) indicator. Full protection features include over-current protection (OCP) with valley current detection to avoid current runaway, short-circuit protection (SCP), input under-voltage lockout (UVLO), output over-voltage protection (OVP), and thermal shutdown. With internal compensation, the MPQ2123 requires a minimal number of readily available, standard external components. It is available in a QFN-11 (2mmx3mm) 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...
