Description:

The FAN5350 Evaluation Board is a compact circuit including the FAN5350 MPX or FAN5350 UCX, a 1µH inductor and one small 4.7µF input and output capacitor. The FAN5350 demo board is a completely assembled and tested surface mount board, providing easy probe access points to all inputs and outputs so that electrical characteristics and waveforms can be easily measured.

Where To Begin:
1 Connect VIN to 5.5V and GND 0V . 2 Use jumper JP1 to select "ON" and "OFF" modes. 3 Verify that the output voltage VOUT, remains constant at 1.82V for varying input
voltages and the load current 4 To measure the supply current in non-switching condition, the FB pin has to be forced
with an external voltage higher than VOUT nominal. VFB = 2V is a good choice. To measure the supply current in switching condition, the digital current meter readings should be averaged until a stable value is displayed. 5 Observe that in OFF mode EN connected to GND the supply current drops below 1µA. A typical value at room temperature is ~50nA provided that there is no leakage current through the PCB. Please ensure the PCB surface is very clean when performing this measurement.
