The EVQ9841A-L-00A evaluation board is designed to demonstrate the capabilities of the MPQ9841A-AEC1. It offers a very compact solution that achieves up to 1A of continuous output current (I_OUT), with excellent load and line regulation across a wide 3.3V to 36V input supply voltage (V_IN) range. The switching frequency (f_SW) can be configured or synchronized to an external clock in the range of 350kHz to 2.5MHz. 

Synchronous operation and an ultra-low, 14μA sleep-mode quiescent current (I_Q) provide high efficiency across the entire I_OUT load range, allowing the MPQ9841A-AEC1 to be used in a variety of step-down applications in both automotive input environments and battery-powered applications.

Peak current mode control provides fast transient response and eases loop stabilization. Excellent low-dropout (LDO) performance allows the MPQ9841A-AEC1 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 whether the output voltage (V_OUT) is within 10% of its nominal voltage.

The EVQ9841A-L-00A is a fully assembled and tested evaluation board. It generates a 5V V_OUT at load currents up to 1A across a 6V to 36V V_IN range, with a 475kHz f_SW.  The MPQ9841A-AEC1 is available in a QFN-16 (3mmx4mm) package with wettable flanks, and is available in AEC-Q100 Grade 1.
