Function
Input (VIN-GIN)
The input voltage can range from 1.8V to 14V. If the input voltage is between 4.5V and 14V
it can supply also the device (through the VCC pin) and in this case the pin 1 and 2 of the
jumper G1 must be connected together.
Output (VOUT-GOUT)
The output voltage is fixed at 3.3V but it can be changed by replacing the resistor R14 of the
output resistor divider:
The over-current-protection limit is set at 15A but it can be changed by replacing the
resistors R1 and R12 (see OCL and OCH pin in Table 3: Pins connection).
VCC-GNDCC
Using the input voltage to supply the controller no power is required at this input.
However the controller can be supplied separately from the power stage through
the VCC input (4.5-14V) and, in this case, jumper G1 must be left open.
VCCDR
An internal LDO provides the power into the device. The input of this stage is the VCC pin
and the output (5V) is the Vccdr pin. The LDO can be bypassed, providing directly a 5V
voltage from VCCDR and Gndcc. In this case the pins 1 and 3 of the jumper G1 must be
shorted.
TP1
This pin can be used as an input or as a test point. If all the jumper G2 pins are shorted, TP1
can be used as a test point of the voltage at the EAREF pin. If the pins 2 and 3 of G2 are
connected together, TP1 can be used as an input to provide an external reference for the
internal error amplifier (see section 4.3. Internal and external references).
TP2
This test point is connected to the Tmask pin (see Table 3: Pins connection).
TP3
This test point is connected to the S/O/U pin (see Chapter 5.10 on page 25).
