EVQ9841-L-00A

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 (IOUT), 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 (fSW) 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 (VOUT) and up to 1A of load current across a 3.3V to 36V input voltage (VIN) range, with a 450kHz fSW.
