The EVQ9841-L-00A is an evaluation board is designed to demonstrate the capabilities of the MP9841 and MPQ9841, which are synchronous, step-down, switching regulators with a 350kHz to 2.5MHz configurable frequency and an integrated, internal high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET).

The MP9841 and MPQ9841 provide up to 1A highly efficient output current (I_OUT), with current mode control for fast loop response. The devices employ advanced asynchronous modulation (AAM) mode to achieve high efficiency at light loads by scaling down the switching frequency (f_SW) to reduce the switching and gate driving losses.

The EVQ9841-L-00A is a fully assembled and tested evaluation board. It generates 3.3V of output voltage (V_OUT) and up to 1A of load current across a 3.3V to 36V input voltage (V_IN) range, with a 450kHz f_SW.

The MPQ9841 is available in AEC-Q100 Grade 1. The MP9841 and MPQ9841 are available in a space-saving QFN-16 (3mmx4mm) package.
