DESCRIPTION
The EV8640DL-00A evaluation board is a fully
assembled and tested PCB that demonstrates the
performance of MP8640, a monolithic step-down
regulator.
The EVB generates a 3.3V output voltage at load
current up to 3A from a 4.5V to 23V input voltage
range, with excellent load and line regulation.
Current mode operation provides fast transient
response and eases loop stabilization.
Fault condition protection includes cycle-by-cycle
current limiting and thermal shutdown.
This device requires a minimum number of
readily available standard external components
and is available in a space saving 3mm x 4mm
14-pin QFN package.
