DESCRIPTION
The EV8758H-L-00A is used for demonstrating
the performance of MP8758H, a fully-integrated,
high efficiency, synchronous step-down switch
mode converter. MP8758H provides up to 10A
continuous output current over a wide input
supply range with constant-on-time control for
fast loop response.
The Evaluation Board can deliver 10A
continuous load current from a 4.5V to 22V
input with excellent load and line regulation.
This part requires minimum number of external
components and is available in QFN21
(3mmx4mm) package
