EV2321-D-00A Evaluation Kit 2A, 19V, Constant-On-Time Step-Down Switcher Evaluation Board
The EV2321-D-00A is used for demonstrating the performance of MP2321, a fully-integrated, high efficiency, synchronous step-down switch mode converter with the feathered 40uA quiescent current. MP2321 provides up to 2A continuous output current over a wide input supply range with constant-on-time control for fast loop response.
High power efficiency over a wide load range is achieved by scaling down the switching frequency at light load to reduce the switching related loss by constant on time control. Short circuit and thermal shutdown provides reliable, fault-tolerant operation.
MP2321 is available in 2mmx3mm 14-pin QFN 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...
