Evaluation PCB
Connectors Pin-OUT
The board has two single row connectors J1 and J2.
• The four pin one (J1) makes possible to supply the board and access to the output voltage easily.
It has the following pin-out:
Pin #
1
2
3
4
Name
V_REF
V_OUT
0
V_C
Description J1 connector
Reference voltage input/output
Output voltage is proportional to the current in the PCB track,
V_OUT = V_REF + G_I*I_P
Note that the output voltage is positive when the current flows inside the
tracks according to the direction marked “I_PÆ” on the PCB
0V
Positive supply voltage 4.75-5.25V; typical consumption 15 mA
• The two pin one (J2) makes possible to access to the fast output voltage and standby input easily.
It has the following pin-out:
Pin #
1
2
Name
V_OUTFAST
Standby
Description J2 connector
V_OUTFAST, fast output signal; note that this output is opposite to V_OUT
(see datasheet for connection)
Standby, Set operating or Standby modes (see datasheet for connection)
Manufacturer and reference for J1, J2: PRECI-DIP, 310-13-120-41-001001.
Thermal Capability
The enclosed evaluation PCB has tracks with thickness of 70 µm.
The dimensions of the tracks drawn on the evaluation PCB lead to some limitations on the maximum continuous
current which can go through the PCB track.
Remark: under normal operating conditions, temperature of some parts of this product might exceed 70°C.
