Evaluation Tools
EV4423-Q-00A Evaluation Kit 3A, 36V, Synchronous Step-Down Converter Evaluation Board
The EV4423-Q-00A is an evaluation board for the MP4423/MPQ4423, a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve 3A of continuous output current, with excellent load and line regulation over a wide input supply range. The MP4423/MPQ4423 has synchronous mode operation for higher efficiency over the output current load range.
Current mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection and thermal shutdown.
The EV4423-Q-00A uses a minimal number of readily available, standard external components, and is assembled and tested in a space-saving QFN-8 (3mmx3mm) package.

SWITCH NODE LAYOUT CONSIDERATIONS FOR EMCThe switch node of a switching regulator or power converter circuit is a critical conduction path that requires special attention when designing the PCB layout. This circuit node is where one or more power semiconductor switches (such as a MOSFET or diode) connect to a magnetic energy-storing device (such as an inductor or transformer winding). The switching signals of this circuit node contain fa...
