The MP9485 employs hysteresis voltage control method to provide fast response to line or load transient. It integrates a high-side high voltage power MOSFET with higher than 0.75A current limit. MPS’s proprietary feedback control scheme minimizes the number of external components.
This board is configured for 5V step-down application. The circuit requires only a minimal number of readily-available, standard, and external components.
