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 4: Pin
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).
