Description:
The FAN5608 Evaluation Board is a compact circuit including either the FAN5608 DMPX/MPX in a 3x3 MLP package or the FAN5608 DHMPX/HMPX in a 4x4 MLP package. Both models are available with either an internal or external Schottky diode which delivers the inductor s stored energy to the load. The FAN5608 demo board, a completely assembled and tested surface mount board, provides easy probe access points to all inputs and outputs so that electrical characteristics and waveforms can be easily measured.
